What are the causes of black spots on the bottom of your foot. How is tinea nigra diagnosed and treated. What are the symptoms of this rare fungal infection. How can you prevent tinea nigra.

Tinea Nigra: A Rare Fungal Infection of the Skin

Tinea nigra is an uncommon fungal infection that manifests as brown or black patches on the skin, primarily affecting the soles of the feet, palms of the hands, and occasionally the torso. This condition is caused by a type of yeast known as Hortaea werneckii, which enters the body through small wounds or breaks in the skin.

The infection is more prevalent in tropical and subtropical regions, making it a concern for residents of these areas and travelers who have recently visited such locations. While tinea nigra is generally harmless and does not pose significant health risks, understanding its characteristics and treatment options is crucial for proper management.

Identifying Symptoms: What Does Tinea Nigra Look Like?

Recognizing the symptoms of tinea nigra is essential for early detection and treatment. The most common signs include:

• A single round, linear, or irregularly shaped patch that grows slowly
• Brown or black discoloration on the affected area
• Patches that may be small and faint, often going unnoticed initially
• Lesions that resemble growing moles or freckles
• Occasional itching, though many cases are asymptomatic

Are tinea nigra lesions always solitary? While most individuals with tinea nigra develop only one lesion, multiple patches can occur if the fungus enters the body through several points, such as wounds on both hands.

Who Is at Risk for Tinea Nigra?

Certain factors increase the likelihood of developing tinea nigra:

• Residence in or travel to tropical or subtropical regions
• Age under 20 years
• History of hyperhidrosis (excessive sweating)
• Recent injuries or skin abrasions
• Frequent contact with wood, soil, or compost, especially in humid environments

The Science Behind Tinea Nigra: Understanding the Causative Agent

Hortaea werneckii, the primary culprit behind tinea nigra, is a fascinating microorganism with unique characteristics. Previously known by various names such as Cladosporium werneckii, Exophiala werneckii, or Phaeoannellomyces werneckii, this yeast thrives in moist environments rich in organic material.

How does Hortaea werneckii infect humans? The fungus typically enters the body through small wounds or breaks in the skin, particularly in areas with numerous sweat glands like the hands and feet. Once established, it remains in the superficial layers of the skin, rarely causing deeper or systemic infections in healthy individuals.

The Role of Stenella araguata in Tinea Nigra

While Hortaea werneckii is the most common cause of tinea nigra, recent research has identified another yeast species, Stenella araguata, as a potential causative agent in some cases. This discovery highlights the importance of accurate diagnosis and the potential for evolving treatment approaches as our understanding of the condition grows.

Diagnosing Tinea Nigra: Ensuring Accuracy and Ruling Out Alternatives

Proper diagnosis of tinea nigra is crucial, as its appearance can mimic other skin conditions, including certain types of skin cancer. How do healthcare professionals confirm a tinea nigra diagnosis?

1. Clinical Examination: A doctor will assess the appearance of the lesion and gather information about recent travel, injury history, and potential exposure to risk factors.
2. Skin Culture: A sample from the affected area is taken and sent to a laboratory. If Hortaea werneckii grows within a week, it confirms the diagnosis of tinea nigra.
3. Skin Biopsy: In some cases, a biopsy may be performed to rule out skin cancer or other conditions that may resemble tinea nigra.

Why is differential diagnosis important in cases of suspected tinea nigra? Given the rarity of the condition and its similarity to other skin disorders, ruling out more serious conditions is essential for appropriate treatment and peace of mind.

Treatment Options: From Home Remedies to Medical Interventions

Treating tinea nigra often involves a combination of topical medications and, in some cases, oral antifungal drugs. What are the most effective treatment approaches?

Home Remedies and Over-the-Counter Options

For mild cases or those seeking to try home treatment first, keratolytic agents may prove effective. These chemicals help remove excess skin and include:

• Wart creams
• Salicylic acid
• Whitfield’s ointment

It’s important to note that these treatments may not be safe during pregnancy, and individuals should consult a healthcare provider before using them.

Prescription Treatments

When home remedies fail or for more severe cases, medical intervention may be necessary. Doctors typically prescribe:

• Topical antifungal creams: Applied directly to the affected area as directed by a healthcare provider.
• Oral antifungal medications: Reserved for large lesions or cases resistant to topical treatments, though their effectiveness may vary.

How long should treatment for tinea nigra last? While the optimal duration is not definitively established, some reports suggest that a one-month treatment period is often sufficient. However, treatment length may vary based on individual cases and response to therapy.

Prevention Strategies: Minimizing the Risk of Tinea Nigra

While tinea nigra is not a severe health threat, preventing infection is preferable to treating it. What steps can individuals take to reduce their risk of developing tinea nigra?

• Practice frequent handwashing, especially after outdoor activities
• Wear gloves when gardening or working with soil and compost
• Avoid walking barefoot outdoors, particularly in tropical regions
• Wear socks or shoes in public areas
• Change socks regularly, especially if they become damp
• Cover any cuts or abrasions on the hands and feet

Why is prevention particularly important for travelers to tropical regions? The increased prevalence of Hortaea werneckii in these environments makes visitors more susceptible to infection, especially if they engage in activities that expose them to soil or organic matter.

Tinea Nigra in the Context of Global Health: Implications and Research Directions

While tinea nigra is generally considered a benign condition, its study contributes to our broader understanding of fungal infections and their impact on human health. How does research on tinea nigra inform global health initiatives?

What future research directions might enhance our understanding of tinea nigra? Potential areas of study include:

• Genetic factors influencing susceptibility to infection
• The potential for Hortaea werneckii to develop antifungal resistance
• The role of climate change in altering the distribution and prevalence of tinea nigra

Living with Tinea Nigra: Patient Perspectives and Quality of Life

While tinea nigra is not life-threatening, it can impact individuals’ quality of life, particularly due to its cosmetic effects. How do patients typically experience living with tinea nigra?

• Psychological impact: Some individuals may feel self-conscious about the appearance of dark patches on their skin.
• Social considerations: Visible lesions may lead to questions or concerns from others, requiring explanation.
• Lifestyle adjustments: Patients may need to modify certain activities or habits to prevent recurrence or spread of the infection.

What support resources are available for individuals diagnosed with tinea nigra? While the condition is rare, patients can benefit from:

• Educational materials provided by dermatology associations
• Online support groups for individuals with rare skin conditions
• Regular follow-ups with healthcare providers to monitor progress and address concerns

The Importance of Patient Education

Educating patients about tinea nigra is crucial for effective management and prevention of recurrence. What key information should healthcare providers emphasize?

• The benign nature of the condition to alleviate unnecessary anxiety
• Proper application of prescribed treatments
• Preventive measures to reduce the risk of reinfection
• The importance of follow-up appointments to ensure complete resolution

By providing comprehensive information and support, healthcare professionals can empower patients to manage their condition effectively and maintain optimal skin health.

Tinea Nigra in Special Populations: Considerations for Unique Cases

While tinea nigra typically affects young individuals in tropical regions, certain populations may require special considerations in diagnosis and treatment. How does the management of tinea nigra differ in these groups?

Pediatric Cases

Children under 20 are more susceptible to tinea nigra. What unique challenges arise in pediatric cases?

• Difficulty in obtaining accurate patient history
• Potential reluctance to comply with topical treatments
• Increased risk of spreading the infection through play and social activities

Healthcare providers treating children with tinea nigra should focus on age-appropriate education and involve parents or caregivers in the treatment process.

Immunocompromised Individuals

While tinea nigra typically remains superficial, immunocompromised patients may be at risk for more extensive or persistent infections. How should healthcare providers approach these cases?

• Closer monitoring of infection progression
• Consideration of systemic antifungal treatments
• Evaluation of potential underlying conditions contributing to immunosuppression

Pregnant Women

Pregnancy can complicate the treatment of tinea nigra due to safety concerns with certain medications. What treatment options are available for pregnant women?

• Safe topical treatments approved for use during pregnancy
• Non-pharmacological interventions to manage symptoms
• Close monitoring to ensure the infection does not worsen

Healthcare providers should weigh the risks and benefits of treatment options carefully when managing tinea nigra in pregnant patients.

The Future of Tinea Nigra Research and Management

Tinea nigra: Diagnosis, treatment, and remedies

Tinea nigra is a very rare fungal infection. It causes brown or black patches to develop on the soles of the feet, the palms of the hand, or, on rare occasions, the torso.

A type of yeast called Hortaea werneckii causes most tinea nigra infections. A person can get the infection when the yeast gets into their body, often through a small wound.

Keep reading to learn more about a tinea nigra infection, including the symptoms, diagnosis, and treatment options.

Tinea nigra causes brown or black patches to appear on the soles of the feet or the palms of the hand. The patches may be so small and faint that a person does not notice them. They also tend to grow slowly. The most common symptoms include:

• a patch on the foot or hand following an injury
• a single round, linear, or irregularly shaped patch that grows slowly
• growing patches that either cause no symptoms or itch
• patches that resemble a growing mole or freckle
• a slow growing brown patch on the torso

The infection affects people who live in tropical regions and those who have recently traveled to these areas.

Most people with tinea nigra have just one lesion. However, if the fungus comes into contact with multiple points of entry, such as wounds on both hands, a person may have several patches.

In healthy people, tinea nigra lives only on the superficial layers of the skin. It does not spread, cause serious infections, or present major health risks. It is more likely to affect young people under the age of 20 years.

Tinea nigra is a fungal infection, which means that a person gets it when they come into contact with a fungus that can cause the infection.

Scientists used to call Hortaea werneckii either Cladosporium werneckii, Exophiala werneckii, or Phaeoannellomyces werneckii. Another yeast called Stenella araguata may cause some cases of tinea nigra.

As with many other fungi, Hortaea werneckii thrives in moist or humid environments. It lives on dead and decaying organic material, such as soil and wood. It can get into the human body when it comes into contact with the skin, usually through a wound. It is most likely to live on parts of the body with many sweat glands, such as the hands and feet.

Certain risk factors increase a person’s likelihood of developing this infection. They include:

• living in a tropical or subtropical region
• recent travel to a subtropical or tropical region
• a history of hyperhidrosis, a condition that causes excessive sweating
• a recent injury
• contact with wood, soil, or compost, such as from gardening without gloves or woodworking in a tropical or subtropical region

In many cases, a person’s symptoms may lead a doctor to suspect tinea nigra. However, as tinea nigra can resemble the symptoms of several other conditions, it is important to get an accurate diagnosis.

The doctor may ask the individual about their recent travel, injury history, and exposure to wood, compost, or soil. They will also usually take a culture of the skin and send it to a lab to see whether Hortaea werneckii grows within a week. If it does, this means that the test is positive for tinea nigra.

Sometimes, a doctor may also perform a skin biopsy to test for skin cancer, as certain types of skin cancer can look similar to tinea nigra.

People who wish to try home remedies may see improvements with keratolytic agents. A keratolytic is a chemical that helps remove excess skin. Some potentially effective keratolytics include:

• wart cream
• salicylic acid
• Whitfield’s ointment

These drugs may not be safe during pregnancy, so women who are pregnant or trying to become pregnant should see a doctor instead of trying home remedies.

If home treatment fails, it is best to see a doctor. There are other possible causes of brown lesions on the skin.

Doctors usually prescribe topical antifungal creams to treat tinea nigra. People should apply the cream directly to the patch exactly as a doctor advises.

In some cases, a person may also need to take oral antifungal drugs, especially if the lesions are very large or if antifungal creams have not worked. However, oral drugs may not be effective.

Doctors do not know what treatment duration is optimal, but the authors of one report suggest that 1 month of treatment is sufficient.

People can reduce the risk of tinea nigra infections by protecting the skin from exposure to soil, compost, and other materials in which the Hortaea werneckii fungus likes to grow. Following this advice is especially important for people who travel to or live in tropical regions.

These strategies can help:

• practicing frequent handwashing, especially after spending time outside
• wearing gloves or other protective gear in the garden
• refraining from walking outside with bare feet
• wearing socks or shoes in public places
• changing socks frequently, especially if they get wet
• covering any wounds on the hands or feet before spending time outside

Several other skin conditions may look similar to tinea nigra. Other fungal infections, such as athlete’s foot, may also cause skin lesions, but they are not usually brown.

Melanoma, a type of skin cancer, can be deadly. It may also look very similar to tinea nigra in the early stages. Similarly to tinea nigra, melanoma is not typically painful at first. Therefore, people who do not get relief from home or medical treatment should see a dermatologist and request a biopsy.

Some other medical conditions and factors that may cause brown patches include:

• skin staining from henna
• skin hyperpigmentation from pregnancy or Addison’s disease
• complications of syphilis
• exposure to certain chemicals, such as silver nitrate

Tinea nigra is not a serious medical condition. Most people do not notice any symptoms other than brown spots on the skin.

However, as tinea nigra looks similar to several other conditions, it is important to see a doctor for an accurate diagnosis.

Prompt treatment can prevent serious skin-related conditions from getting worse.

Red dark spots (dots) on the legs with diabetes: treatment.

Redness and rash on the fingers and lower legs

Spots on the legs in diabetes mellitus occurs in 60% of diabetic patients.

Often it is the reddening of the skin that is the first wake-up call about the problems of the endocrine system.

Localization of spots in the area of ​​the feet with almost one hundred percent probability indicates the onset of the disease diabetic foot.

Why do the legs hurt in diabetes, spots appear in the area of ​​the limbs and how to treat them? We will tell in this article.

Where does diabetic foot rash occur?

Modern medicine has about 35 different complications of diabetes, which manifest themselves in the form of dermatoses.

Physicians classify these manifestations into:

1. Primary. Appeared immediately after an increase in blood sugar levels.
2. Secondary. Arises due to infection of the skin.
3. Tertiary. Periodically appearing as a result of taking medications and in the presence of other provoking factors.

The rash on the legs can have different localization and have the following features:

• the lesion may extend to the lower leg and upper thigh, or may be limited to the foot only;
• the rash may affect one or both legs;
• spots may be accompanied by tissue death (peeling) and other symptoms;
• the intensity of the spots depends on the age of the patient: in the elderly, a rash occurs much more often;
• skin problems often occur in the absence of mechanical damage.

Important! Any skin rashes on the legs, changes in the color and structure of the skin are the first signs of a diabetic foot. If you have these symptoms, you should immediately contact a specialist.

Why do spots appear on the legs with diabetes?

Dermatologists and podiatrists note that the most common types of skin lesions are:

1. Acantokeratoderma.

A disease characterized by keratinization and darkening of the skin around the feet. Diabetes mellitus, dark spots on the legs appear after redness, in this case it is a provocative sign.

It is very easy to prevent the development of acanthosis derma, it is enough to use moisturizers that reliably retain moisture inside the cells of the epidermis, effectively moisturizing the skin. Such products contain a natural moisturizer – urea.

For example, a series of creams “DiaDerm” is designed specifically for diabetics to prevent dryness and keratinization of the skin.

2. Dermatopadia.

Damage to the skin in the area of ​​the lower leg and ankle. The disease manifests itself as brown and red spots on the shins of the legs in diabetes, which, as a rule, do not cause pain to the patient.

In this case, it is important to ensure that the dermatopadia does not develop into a more serious disease. Prevention of the development of the disease is the use of a protective cream with an antibacterial effect to prevent infection. Protective cream is perfect for this.

3. Xanthomosis.

Appears as yellowish-white plaques on the surface of the legs. Usually, the appearance of plaques is preceded by ulcers on the legs in diabetes, which are surrounded by a dark rim. After some time, plaques form at the site of the ulcers.

The reason for their appearance is a violation of lipid metabolism against the background of general endocrine disorders. Treatment and prevention of xanthomosis is the normalization of metabolism and fat metabolism in tissues.

4. Lipoid necrobiosis.

In this disease, the upper layers of the epidermis die off. There are no pronounced pains, and the patient is more concerned about the unsightly appearance of the affected area of ​​the foot.

The reason for the development of necrobiosis is considered to be an insufficient supply of oxygen to tissues. As a treatment, physiotherapy is used to normalize blood flow.

With this type of leg skin lesion, the patient should regularly visit a specialist for the timely diagnosis of gangrene and malignant degeneration of necrotic areas.

5. Diabetic blisters (blisters).

One of the dermatological complications of diabetes, which manifests itself in the form of blistering formations in the feet. The disease begins with the fact that the patient’s toes are reddened due to diabetes and there is a slight itching at night.

After a while, yellowish-transparent blisters form at the site of redness. In no case should you pierce the bubbles and try to squeeze the liquid out of them! This can lead to infection and inflammation.

The treatment is prescribed by a dermatologist and consists in the use of antiseptic ointments.

6. Vitiligo.

This disease is more common than others. The disease manifests itself in the form of extensive white spots due to the loss of pigment, which ceases to be produced during metabolic disorders.

Vitiligo not treated, i.e. It is impossible to return the lost pigment to the skin. Treatment is reduced to the normalization of metabolism in order to prevent the spread of white spots.

7. Fungal infections.

Most often, diabetics encounter a fungus such as Candida Albicans, which causes candidiasis. The infection manifests itself as red dots on the legs with diabetes, unbearably itchy.

Dirty and wet shoes, lack of a natural protective layer of the epidermis contribute to the development of infection. Treatment of the fungus is carried out locally using antifungal sprays and ointments.

To protect against infection, it is recommended to follow the rules of hygiene and use the “Protection” cream, which forms a film on the skin and protects against infection.

8. Skin itching.

Occurs in response to some kind of irritant or is an early symptom of many dermatological diseases. In the treatment of itching, simple rules for foot care in diabetes help, which recommend daily care, proper nutrition and the selection of special shoes.

If itching is so severe that it causes scratching or worsens the quality of life (keeps you up at night, etc. ), then you should consult a dermatologist to determine the cause of the itching and treat it.

9. Subcutaneous hematomas.

They are dark brown-purple spots with a diameter of no more than 5 cm. Hematomas appear when the vessels are damaged, which happens quite often, because. diabetic patients experience increased stress.

The frequent appearance of hematomas is an alarm signal indicating problems with blood flow in the extremities. Treatment should be carried out under the supervision of a phlebologist who will prescribe medications and physiotherapy to normalize blood circulation.

10. Black acanthosis.

Dark spots on the legs are rare in diabetics. Their presence indicates the appearance of malignant tumors on the surface of the skin or in the muscle layer. This formidable disease usually develops at the site of long-term insulin injections.

Treatment depends on the type and location of the growth. Prevention of acanthosis lies in the proper treatment of injection sites.

Each of the above diseases in the absence of timely treatment can lead to the development of gangrene, so any redness on the leg with diabetes is a reason to see a doctor.

Rash and red spots on the feet in diabetes: treatment and first signs

Treatment of dermatological lesions of the foot in diabetes always begins with the normalization of sugar levels in the bloodstream. At the initial stage of the disease and with proper care, these measures are sufficient, and the symptoms disappear.

If red spots on the legs in diabetes mellitus are accompanied by pain, then painkillers (analgesics) and ointments containing lidocaine or novocaine are used as painkillers.

If an infection or fungus is present, appropriate therapy is given with antibiotics and antifungals. Wounds and ulcers are treated with hydrogen peroxide and furacilin ointment.

It is very important to use foot relief during the treatment. Such means are insoles “Unloading”, which distribute and reduce the load on the legs.

Click on the picture below to learn more about diabetic foot insoles and order them for home delivery or mail order.

Of course, not every redness of the toes in diabetes indicates the development of skin diseases. Sometimes the fingers and feet turn red due to overheating or allergies.

When redness occurs, it is recommended to use a special “Regenerating” cream, which helps to eliminate irritations. If after 2-3 the redness becomes darker, itching or other symptoms appear, then you need to urgently contact a dermatologist.

Pressure sores on the heels: how to treat? Formations on the heels of black color in bedridden patients (photo)

Bedsores on the heels of black color occur in bedridden patients not only at home, but also in the hospital and represent dead areas of the heel skin. The development of bedsores occurs with prolonged squeezing of soft tissues and skin between the calcaneus and the surface of the bed. Most often, black bedsores on the heels occur in patients with prolonged immobility, especially against the background of circulatory disorders. Trophic heel ulcers are treatable, but some never fully heal. Bedsores are easier to prevent than to cure. The degree of damage to the skin and tissues ranges from reddening of the skin to a deep necrotic wound involving the bone. Many patients and their relatives try to treat pressure sores on the heels at home. Such an approach can bring success at an early stage of the development of the disease, however, with the development of the process deep into the calcaneus, it becomes impossible to cure such a bedsore without complex reconstructive plastic surgery.

Stages and symptoms

Pressure ulcers can develop rapidly, but pressure sores and ulcers develop through four stages (each with its own symptoms):

• Stage 1

Redness of intact skin. It is slightly inflamed and may be painful, itchy, and warm to the touch. You may also notice that the texture of the skin has changed slightly. At this stage, bedsores on the heels resemble a sunburn. This initial stage is difficult to detect in people with dark skin.

• Stage 2

In the second stage, the first signs of skin damage appear. They look like abrasions, blisters, or small pits. The outer layer of the skin is broken, red and painful. Surrounding tissue may be pale, red, and swollen. The upper layers of tissues, as the most damaged, begin to die and peel off. Bruising at this stage indicates a suspicion of possible deeper tissue damage, involvement of fat or muscle tissue.

• Stage 3

Complete loss of tissue. The damage extends to the deeper tissue layers on the heel. There are crater ulcers that are prone to infection. Subcutaneous fat may be visible, but bones, tendons, or muscles are not affected. The depth of the ulcer of the 3rd stage depends on its anatomical position. Most often, bedsores on the heels go up to stage 3, until they are noticed by others and begin to be treated.

• Stage 4

Tissue loss, bone and tendon exposure. Ulcers with black edges extend to the calcaneus and can lead to the development of osteomyelitis (purulent-necrotic process in the bone). The open calcaneus is visible or directly palpable at the bottom of the trophic ulcer. These ulcers are extremely difficult to heal and may take many months and actions to heal. Therefore, more seriously should be taken to prevent the development of ulcers.

Complications

Complications of pressure ulcers (especially pressure ulcers) can be life threatening and include:

• Phlegmon

Acute purulent inflammation of the skin and soft tissues. People with nerve damage (neuropathy) or after a spinal injury often do not feel pain in the area affected by inflammation and pressure sores. Phlegmon can cause severe intoxication and even general blood poisoning (sepsis).

• Heel ulcer

Chronic wound of the heel that does not heal for a long time, significantly impairs the patient’s quality of life, as it leads to dysfunction of support and walking. A trophic heel ulcer can occur as a result of a bedsore, and not only in spinal patients, but also in postoperative and post-resuscitation patients due to their prolonged immobilization.

• Bone and joint damage

Ulcer infection can affect joints and bones. Infection in the joint cavity can cause a general infection of the blood. Bone infections (osteomyelitis) can reduce lead to destruction of the heel bone.

• Cancer

Wounds that do not heal for a long time can develop into squamous cell skin cancer over time.

• Sepsis

General blood poisoning develops with a weakened immune system, diabetes mellitus and other serious concomitant diseases and is often the cause of death.

Prevention and prognosis

Movement constantly redistributes pressure on our body. If an illness or injury restricts our mobility, pressure builds up in certain areas of the body, and blood circulation decreases. This can lead to death of the skin and tissues, creating bedsores and ulcers. To reduce the risk, it is necessary to use anti-decubitus systems and devices that relieve pressure on bony prominences.

Wound healing on the heel is delayed due to the immobile position of the patient, poor trophism due to vascular lesions and the general condition of the body. Improper wound care, a variety of folk recipes adversely affect the patient’s condition. The bedsore is complicated by damage to the surrounding soft tissues, infection and purulent discharge. A long-term purulent-destructive process leads to a deterioration in the general condition, a violation of the absorption of nutrients. In a patient without proper care, new bedsores form in other parts of the body, which aggravate the pathological process.

However, simple treatments can help prevent these painful and dangerous problems.

• Skin care:

Examine the patient’s skin several times a day. Pay special attention to the heel areas and other pressure points on the body. Minimize moisture contact with the body. Keep skin clean and dry. Rinse with a mild cleanser, care oil and dry thoroughly. Perform hygiene procedures as soon as possible, washing with soap and water to limit skin exposure to moisture, urine and feces. Change bedding and clothes promptly. Make sure that there are no wrinkles on the bed linen and clothes under the patient.

• Protect skin from injury:

Avoid massaging soft tissue lesions over bony prominences. Change body position at least every 2 hours. Reduce friction. If the patient is bedridden, the head of the bed should be raised as little as possible. When it rises above 30 degrees, a person can slip on the surface of the bed, damaging tissues and small blood vessels.

Pillows and special pads should be used to avoid touching the knees and ankles when turning the patient on their side. If the patient is completely immobile, pillows should be placed under the feet from mid-calf to ankle to take pressure off the heels. Never put pillows under your knees. This impairs blood circulation.

• Eat well:

A balanced diet is very important for skin health at all stages of treatment. Healthy tissue is less susceptible to damage. In cases of abrasions and abrasions, treat defects with antiseptic preparations.

• Improve patients’ ability to move:

A rehabilitation program can help some people get back in shape quickly.

• Shift weight and position frequently:

If you use a wheelchair, try shifting your weight about every 15 minutes. Rise up if possible. If you have enough strength in your arms, do a push-up – lifting your body off the seat, leaning on the armrests of the chair. Bedridden patients may experience discomfort, pain, social isolation, or depression. Try to find something for your physical abilities.
