Things you can do to help boils

There are things you can do to treat boils yourself and stop them coming back.

Do

• soak a clean cloth in warm water and hold it against the boil for 10 minutes 4 times a day

• clean the area around the boil with antibacterial soap if pus comes out

• cover the area with a dressing or gauze until it heals

• bathe or shower every day and wash your hands regularly

• take paracetamol or ibuprofen to ease the pain

• wash your towels and bedding at least once a week at high temperature

• try to lose weight if you are very overweight and have boils between folds of your skin

Don’t

• do not pick, squeeze or pierce a boil

• do not share your towel with other people until the boil has gone

• do not go to a swimming pool or gym until the boil has gone –⁠ you could pass the infection on to others

Non-urgent advice: See a GP if:

• you’ve had a boil for 2 weeks and the things you’ve tried are not helping
• you keep getting boils
• you have a group of boils (carbuncle)

Urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if you have a boil and:

• it is on your face
• the skin around your boil feels hot, painful and swollen
• you feel hot and shivery
• you have a weakened immune system – this could be from taking treatments such as steroids, or having a condition like diabetes

You can call 111 or get help from NHS 111 online.

Treatment for boils

A GP can check if you need treatment.

You may need:

• a small procedure to drain the boil to get rid of the pus
• antibiotics

Causes of boils

You may be more likely to get boils if you have a long-term condition that affects your immune system, such as diabetes or HIV.

You may also be more likely to get boils if:

• you’re a man
• you’ve been in close contact with someone with boils
• you have certain skin conditions, such as eczema
• you take certain medicines, such as steroids
• you’re living with obesity or malnutrition

Carbuncles are less common and mostly affect middle-aged men.

Furuncles and carbuncles: Symptoms, causes, and treatment

A skin abscess happens when pus collects in hair follicles, skin tissues, or under the skin. A furuncle, also known as a boil, is a painful infection that forms around a hair follicle and contains pus.

A carbuncle is collection of boils that develop under the skin. When bacteria infect hair follicles, the follicles can swell and turn into boils and carbuncles.

A furuncle starts as a red lump. It may be tender. The lump rapidly fills with pus, and as it grows it may burst.

Furuncles, boils, and carbuncles typically affect the thighs, armpits, buttocks, face, and neck.

Individuals with weakened immune systems, adolescents, and young adults are more susceptible to furuncles than younger children or older adults.

Furuncles and carbuncles are similar but with some differences.

Furuncles, or boils, are skin abscesses that result from staphylococcal infection. They affect a hair follicle and surrounding tissue.

Carbuncles are groups of furuncles that join together under the skin. They affect the deeper layers, and they can lead to scarring.

Furuncles and carbuncles both result in swelling under the skin, and there may be other symptoms, too.

Furuncles

Furuncles develop rapidly as pink or red bumps. They are often painful. The surrounding skin is typically red, inflamed and tender.

The lesions often appear on the neck, breast, face, buttocks, or thighs. They occur in places prone to hair, sweat, and friction, and they tend to start in a hair follicle.

The bump fills with pus within a few days, and it grows. The bigger it gets, the more painful it becomes.

Furuncles may go away without any intervention. Sometimes they burst and heal without a scar within 2 days to 3 weeks.

They are common among teenagers and young adults, and they affect males more than females. Overcrowded and unhygienic living conditions increase the risk.

Carbuncles

A carbuncle is less common than a furuncle, or boil. It is a collection of boils on one site. It is larger than a single boil, measuring up to 4 inches across. A carbuncle usually has one or more openings that drain pus onto the skin.

The most common cause of a carbuncle is a bacterium known as Staphylococcus aureus (S. aureus). The infection may lead to generalized body symptoms, including a fever of 100.4 degrees Fahrenheit or higher, and a general feeling of being unwell, weak, and exhausted.

The infection can spread to other parts of the body, and it can spread to other people too, so that other household members may develop one at the same time.

Carbuncles are most likely on the back, the thighs, or the back of the neck.

They affect males more frequently than females, and especially older men with poor health or a weakened immune system.

Carbuncle infections tend to be deeper and more severe than those caused by furuncle. The risk of scarring is higher, and they take longer to develop and to resolve than furuncles.

S. aureus, also known as staph bacteria, live on the skin and inside the nose and throat.

Usually, the body’s immune system keeps them under control, but sometimes they enter the skin through a hair follicle, or through a cut or graze in the skin.

When the skin becomes infected, the immune system responds by sending white blood cells to the affected area to destroy the bacteria. Pus is an accumulation of dead bacteria, dead white blood cells, and dead skin.

The following conditions increase the risk of developing furuncles:

• Diabetes: High levels of blood sugar, or glucose, can reduce the immune system’s ability to respond to infection.
• Medications: Some medications weaken the immune system.
• HIV and some other diseases: Certain conditions weaken the immune systems
• Skin conditions: Psoriasis, eczema, and acne increase susceptibility.

Obesity also increases the risk.

Often, the normal bacteria in a person’s nose or on their skin can lead to an abscess. Sometimes, however, the infection can spread when people share space, materials, or devices, such as clothing and whirlpool footbaths.

A number of solutions can help relieve the symptoms of skin abscesses.

Applying a warm face cloth for 10 minutes a few times a day may help speed up the healing process. Heat draws more blood, and so more whites cells, to the affected area and encourages pore dilation and release of pus.

It is important to wash the hands thoroughly after touching the site and to avoid squeezing a furuncle or carbuncle, as this increases the risk of spreading infection.

Experts say patients should not try to burst or squeeze furuncles or carbuncles. If the lesion is very painful, if it lasts for more than 2 weeks, or if there is a fever, you should see your doctor.

There is a risk of secondary infection, which is when the infection spreads to other parts of the body. Cellulitis is one type of potentially serious secondary infection that can occur.

When to see a doctor

A furuncle usually goes away after around 2 weeks without treatment, but if a fever accompanies the abscess, the person should seek medical help.

Patients with a chronic disease, such as diabetes or cancer, or those who are taking immunosuppressive medications, should consult their doctor if they have a carbuncle.

Ways of preventing boils and carbuncles include:

• keeping the skin clean by washing it regularly
• immediately cleansing all skin wounds, cuts, and grazes, however small
• putting a sterile bandage over any cuts to help prevent infection

Eating a healthy, well-balanced diet and getting regular physical exercise will improve your general health and your immune system, reducing the risk of developing furuncles and carbuncles.

Furuncle and furunculosis

Furuncle is an acute purulent inflammation of the hair follicle involving the surrounding tissues (sebaceous gland, adipose tissue). The cause of the formation of a boil is most often golden, and less often white staphylococcus aureus. Predisposing factors are minor mechanical injuries, clothing friction, especially on the neck, lower back, buttocks, as well as exhaustion, diabetes, obesity, constant hypothermia or overheating, and others.

There are single furuncle, recurrent single furuncle (appears in one place after a short period of time) and furunculosis (many boils occur simultaneously or one after one).

Clinical picture

First, an inflammatory infiltrate appears around the hair follicle with indistinct borders of bright red color with moderate pain. Then the infiltrate thickens, becomes more painful, and the surrounding tissues swell. On day 3-4, the boil increases to 1-3 cm in diameter, in the center of which a purulent-necrotic core with a pustule on the surface is formed, the skin over it turns red, and the temperature rises locally on palpation. Also at this time, general symptoms of intoxication join (general weakness, headaches, fever up to 37-38 ° C, etc.). With a favorable course, the lid of the pustule can open and purulent content with an admixture of blood with a necrotic core is released from the boil. Then healing occurs, the process usually lasts 8-10 days.

But we must remember that boils in an unfavorable course can lead to abscess formation or the formation of gangrene, lymphangitis or lymphadenitis, sepsis, infection metastasis to the liver, kidneys and other organs. Boils on the face are especially dangerous for the development of meningitis.

Important! It is impossible not only to squeeze out, but also to massage the inflammatory infiltrate of any localization, especially on the face. There is no need to self-medicate, the treatment of a boil should be entrusted to a specialist.

How to treat a boil?

Single uncomplicated boils are treated conservatively. Care is prescribed for the site of the lesion, ointment dressings, antibacterial and anti-inflammatory therapy. In some cases, injections are performed with solutions of antibiotics and anesthetics (painkillers).

When abscessing a boil, it is necessary to turn to the methods of outpatient surgery. Surgical intervention consists in opening the abscess under local anesthesia, its sanitation and subsequent drainage.

Furunculosis – purulent-necrotic inflammation of the hair follicle and surrounding subcutaneous fat. It is formed on the hairy parts of the skin. The causative agent of infection is usually Staphylococcus aureus.

Furunculosis is more common in people with weakened immune systems, teenagers and adults. Furunculosis in children and the elderly is rare. The disease affects men more than women. Unsanitary living conditions increase the risk of infection.

Boils may disappear without any treatment. Sometimes they burst on their own and heal without a trace within 2 days to 3 weeks. However, after healing, they can lead to such a complication of furunculosis as scars. If an abscess is accompanied by fever, pain, or other symptoms that affect well-being, a person should seek medical attention.

Three or more episodes within 12 months is defined as recurrent furunculosis. In this case, you should also see a doctor, even if boils tend to heal on their own.

Symptoms of furunculosis

Furuncles are red, swollen and painful nodules of various sizes. The more they become, the more painful the sensation. The surrounding skin is usually red and inflamed. The nodules quickly fill with pus and at the last stage of furunculosis can burst. If several adjacent follicles are infected, they may coalesce and form a larger knot called a carbuncle. A carbuncle is a collection of boils.

Fever and swollen lymph nodes are rare in furunculosis, but possible.

Boils and carbuncles commonly affect the thighs, armpits, buttocks, face and neck. They occur in areas prone to hair formation, sweat and friction.

Causes of furunculosis

Staphylococcus bacteria that cause infection live on the skin, concentrating in parts of the body where folds are present (furunculosis on the face, in particular, furunculosis of the nose and furunculosis of the lips are the most common places of manifestation of the disease). Usually the immune system keeps them under control, but in a weakened immune system, they enter the skin through a hair follicle, a cut or abrasion in the skin. Furunculosis can be provoked by a simple injury to the skin or by combing it. Boils are often the result of poor personal hygiene. When the skin becomes infected, the immune system responds by sending white blood cells to the affected area to destroy the bacteria. Pus is a collection of dead bacteria, dead white blood cells, and dead skin.

The following conditions increase the risk of skin furunculosis:

• Diabetes: High blood sugar or glucose levels can reduce the ability of the immune system to respond to infection.
• Medicines: Some medicines weaken the immune system.
• HIV and other diseases that affect the immune system.
• Skin diseases: psoriasis, eczema and acne.
• Being overweight also increases the risk.

Furunculosis itself is not contagious by contact, but in immunocompromised individuals, infection can sometimes spread when people share the same space or materials, such as clothing and foot spas.

How to treat furunculosis?

We note right away that the treatment of furunculosis should occur only with a doctor who has the appropriate training and equipment. Only he can choose a treatment regimen for furunculosis in each individual case.

Do not try to burst or squeeze boils or carbuncles yourself! If the lesion is very painful, if it lasts more than 2 days, or if there is a fever, you should ask your doctor how to cure furunculosis in your particular case.

Furunculosis: professional treatment

The doctor prescribes tests for furunculosis – smears of cultures from the affected area (from boils obtained by incision), as well as from carrier areas on the skin.

Sometimes a complete blood count is done to determine the cause of a skin infection and determine the most effective treatment for furunculosis, as well as to rule out another internal disease. Immunological evaluation may be considered for disease recurrence or signs of another disease.

Your doctor may use a sterilized needle to pierce a boil abscess and drain the pus. Pricking may be enough to clear a furunculosis, but if the infection has spread to a deeper layer under the skin, your doctor may prescribe antibiotics.
