Does deep vein thrombosis pain come and go. How to distinguish DVT from other conditions with similar symptoms. What are the key differences between DVT and peripheral artery disease, varicose veins, spider veins, and cellulitis.

Understanding Deep Vein Thrombosis (DVT): Symptoms and Risk Factors

Deep Vein Thrombosis (DVT) is a serious condition characterized by the formation of blood clots in deep veins, typically in the legs. Recognizing the symptoms of DVT is crucial for early diagnosis and treatment. The primary indicators of DVT include:

• Unequal swelling, with one leg larger than the other
• Pain or tenderness when standing or walking
• Warmth in the affected area
• Red or discolored skin

It’s important to note that about half of DVT cases are asymptomatic, making it a potentially silent threat. The risk of DVT increases with certain factors such as:

• Injury to a vein
• Prolonged immobility
• Hormonal treatments
• Pregnancy
• Chronic diseases
• Family history of DVT
• Obesity
• Recent surgery
• Inherited blood clotting disorders

Does DVT pain fluctuate? While DVT symptoms can vary in intensity, persistent discomfort is common. If you experience sudden relief followed by recurrence of symptoms, it’s crucial to seek medical attention promptly.

Peripheral Artery Disease (PAD): A Condition Often Confused with DVT

Peripheral Artery Disease (PAD) shares some similarities with DVT but has distinct characteristics. PAD occurs when arteries in the legs become narrowed due to plaque buildup, restricting blood flow to the limbs. Key symptoms of PAD include:

• Pain, numbness, or heaviness in legs during walking
• Cramps in feet, legs, or buttocks
• Non-healing sores on feet or legs
• Pale or bluish-colored skin
• Temperature difference between legs

How does PAD differ from DVT? Unlike DVT, which affects veins, PAD primarily impacts arteries. Additionally, PAD symptoms often worsen with physical activity and improve with rest, while DVT pain tends to be more constant.

Risk Factors and Long-term Implications of PAD

PAD shares risk factors with heart disease, including smoking, diabetes, high blood pressure, and high cholesterol. While not immediately life-threatening like DVT, PAD can lead to serious complications such as gangrene and increases the risk of heart attack and stroke.

Varicose Veins: Superficial Vein Issues vs. Deep Vein Thrombosis

Varicose veins, often mistaken for DVT, are enlarged, twisted veins visible just beneath the skin’s surface. They occur when valves in the veins become weak or damaged, causing blood to pool. Symptoms of varicose veins include:

• Swollen ankles and feet
• Throbbing or cramping in legs
• Itchy lower legs or ankles
• Aching, painful legs
• Feeling of heaviness in legs

How can you differentiate varicose veins from DVT? Unlike DVT, varicose veins are visible on the skin’s surface and rarely lead to serious complications like pulmonary embolism. The pain associated with varicose veins is typically more diffuse and less severe than DVT-related pain.

Treatment Options for Varicose Veins

While varicose veins are generally not a serious medical concern, they can cause discomfort and affect quality of life. Treatment options range from conservative measures like compression stockings to more invasive procedures such as sclerotherapy or laser treatment.

Spider Veins: Cosmetic Concern or Medical Issue?

Spider veins, a milder form of varicose veins, are small, dilated blood vessels visible near the skin’s surface. They typically appear as web-like patterns on the legs or face. Key characteristics of spider veins include:

• Blue or reddish color
• Web-like or branching appearance
• Usually painless
• No swelling or warmth in the affected area

Are spider veins a sign of DVT? Spider veins are generally harmless and do not indicate DVT. Unlike DVT, which occurs in deep veins and can be life-threatening, spider veins are a superficial condition primarily causing cosmetic concerns.

Managing Spider Veins: When to Seek Treatment

While spider veins don’t pose health risks, some individuals may seek treatment for aesthetic reasons. Options include sclerotherapy, laser therapy, and topical treatments. Consult a dermatologist or vascular specialist to discuss the most suitable approach for your situation.

Cellulitis: A Skin Infection Mimicking DVT Symptoms

Cellulitis is a bacterial skin infection that can present symptoms similar to DVT. This condition occurs when bacteria enter through a break in the skin, causing inflammation. Common symptoms of cellulitis include:

• Red, swollen, warm skin
• Tenderness and pain in the affected area
• Fever and chills
• Fatigue and drowsiness
• Possible skin blistering or dimpling

How can you tell cellulitis apart from DVT? While both conditions can cause redness, swelling, and warmth in the affected area, cellulitis is typically accompanied by fever and affects the skin more superficially. DVT pain is often more localized and may worsen with standing or walking.

Treating Cellulitis: The Importance of Prompt Medical Care

Cellulitis requires immediate medical attention to prevent the infection from spreading. Treatment typically involves antibiotics, either oral or intravenous, depending on the severity of the infection. Unlike DVT, cellulitis does not carry the risk of pulmonary embolism but can lead to serious complications if left untreated.

Vasculitis: An Inflammatory Condition with DVT-like Symptoms

Vasculitis is a group of disorders characterized by inflammation of blood vessels. This condition can affect various parts of the body and present symptoms that may be confused with DVT. Key features of vasculitis include:

• Inflammation of blood vessels
• Reduced blood flow to organs and tissues
• Various symptoms depending on the affected area
• Possible autoimmune origin

Can vasculitis be mistaken for DVT? While some forms of vasculitis can cause leg pain and swelling similar to DVT, vasculitis often presents with more systemic symptoms such as fever, fatigue, and joint pain. Additionally, vasculitis can affect multiple areas of the body, unlike DVT which typically occurs in one leg.

Diagnosing and Managing Vasculitis

Diagnosing vasculitis often requires a combination of blood tests, imaging studies, and sometimes tissue biopsies. Treatment varies depending on the type and severity of vasculitis but may include corticosteroids, immunosuppressants, and targeted therapies. Unlike DVT, which is treated with anticoagulants, vasculitis management focuses on controlling inflammation and preventing organ damage.

Seeking Medical Attention: When to Consult a Healthcare Professional

Given the potential seriousness of DVT and the similarity of its symptoms to other conditions, it’s crucial to seek medical attention if you experience persistent leg pain, swelling, or redness. A healthcare professional can perform the necessary tests to differentiate between DVT and other conditions, ensuring appropriate treatment.

When should you seek emergency care? If you experience sudden shortness of breath, chest pain, or coughing up blood along with leg symptoms, seek immediate medical attention as these could indicate a pulmonary embolism, a life-threatening complication of DVT.

Diagnostic Procedures for Suspected DVT

To diagnose DVT, doctors may use a combination of clinical assessment, blood tests (D-dimer), and imaging studies such as ultrasound or venography. These tests help distinguish DVT from other conditions with similar symptoms, ensuring accurate diagnosis and appropriate treatment.

By understanding the nuances of DVT symptoms and how they differ from other conditions, individuals can better advocate for their health and seek timely medical care. Remember, while many conditions can mimic DVT, only a healthcare professional can provide a definitive diagnosis and appropriate treatment plan.

4 Conditions With Similar Symptoms to DVT

• Deep Vein Thrombosis
• Peripheral Artery Disease (PAD)
• Varicose Veins
• Spider Veins
• Cellulitis
• Vasculitis
• Acute Arterial Occlusion
• Necrotizing Fasciitis
• Nephrotic Syndrome
• Congestive Heart Failure
• Lymphedema
• Venous Stasis
• Acute Compartment Syndrome
• Superficial Thrombophlebitis

You may have DVT, deep vein thrombosis, if you notice that one limb is swollen, painful, warm, and red. But many other things can cause similar symptoms. Some of them, like minor cuts, fractures, or sprains, are relatively harmless, and others are more serious. You’ll need to see a doctor to find out what’s going on and what treatment is needed. Learn about some of these conditions below.

You can get DVT at any age, and several things can cause it. Some of them are:

• Injury to a vein
• Anything that immobilizes you, such as bed rest, hospitalization, recovery from an injury
• Paralysis
• Birth control pills
• Hormone replacement therapy
• Pregnancy
• Chronic diseases like heart disease, lung disease, cancer, Crohn’s disease, or ulcerative colitis
• Family history of DVT or pulmonary embolism
• Obesity
• Surgery
• A blood clotting disease that you inherit

DVT normally affects just one leg. Symptoms include:

• Unequal swelling, where one leg is larger than the other
• Pain or tenderness when you stand or walk
• Warmth
• Red or discolored skin

About half of people who get DVT won’t have any signs. You may not know you have a clot unless a piece of it breaks off and travels to your lung. That’s a medical emergency called a pulmonary embolism. Call 911 right away if you have:

• Shortness of breath
• Pain when you take a deep breath
• Coughing up blood
• Racing heart rate
• Rapid breathing

You get this when the arteries in your legs become hard and narrow. In PAD, plaque builds up in the arteries. Over time, it can block blood flow to your arms and legs. When this condition affects veins instead of arteries, it’s called peripheral vascular disease (PVD).

Some of the symptoms are:

• Pain, numbness, aching, or heaviness in your legs when you walk
• Cramps in your feet, leg, or butt
• Sores or wounds on your feet or legs that don’t get better
• Pale or bluish-colored skin
• One leg feels cooler than the other.

PAD isn’t a medical emergency, but lack of blood flow to your legs can cause serious problems like gangrene. That’s when the tissue in your leg dies.

You’ll also have a greater risk for heart disease, heart attack, and stroke. But when you make changes to manage your condition, you’ll lower your chances of getting those, too. The same risks that lead to heart attacks and strokes also cause PAD. They include smoking, diabetes, high blood pressure, and high cholesterol.

Unlike DVT, these appear just beneath the surface of your skin. You get them when the valves inside your veins become weak or damaged. Normally, the valves help blood flow to your heart. When they don’t work right, blood pools inside your veins. They swell and become large and rope-like. That’s another difference from DVT — the surface-level clots that come with varicose veins are uncommon and don’t usually break free and travel to your lungs. When DVTs do this, it’s called a pulmonary embolism, and it can be fatal.

If you have varicose veins, you’ll notice:

• Swollen ankles and feet
• Throbbing or cramping in your legs
• Itchy lower legs or ankles
• Achy, painful legs
• Heaviness in your legs

Varicose veins aren’t serious. Talk to your doctor about treatments.

These are a smaller type of varicose veins. They affect your capillaries, the smallest blood vessels in your body.

You’re most likely to get these on your legs or face. They look like a spider web or the branches on a tree. They’re usually a blue or reddish color. You may not like how they look, but they don’t cause any medical problems.

And because they’re like varicose veins, spider veins also differ from DVT because they’re close to the surface and don’t tend to break free and move into your lungs.

Here, bacteria infect the skin. The first signs can mirror DVT, with skin that’s red, swollen, warm, and sensitive to the touch. Other possible symptoms, like chills, fever, nausea, drowsiness, and trouble thinking, are less likely in DVT. The same goes for the red streaks, bumps, or sores that might appear on your skin.

Get care right away if you notice these signs, because it can be very serious if you don’t treat it.

It’s inflammation of the blood vessels. This can lessen essential blood flow to your organs and other tissue. There are almost 20 versions of the disease, but all seem to happen when your immune system mistakenly attacks healthy tissue (autoimmune disease). Doctors don’t know exactly what causes it, though possible triggers appear to include genes, medication, infection, environment, allergies, and other illnesses.

Symptoms vary by person and the type of disease, but may include:

• Rashes or skin lesions (more than just the swelling and darkening in DVT)
• Pain: Aches in your muscles, belly, joints, or head (uncommon in DVT except in affected limb)
• Lack of appetite and weight loss (uncommon in DVT)
• Tiredness and fever (uncommon in DVT)
• Blurry vision, eye pain, and redness (uncommon in DVT)
• Ear or sinus problems that don’t go away (uncommon in DVT)
• Shortness of breath and coughing (could cough up blood)
• Tingling, numbness, weakness, and nerve pain (neuropathy) (uncommon in DVT)
• Bloody or dark-colored urine (could be kidney problems) (uncommon in DVT)

It means a blocked artery, and it typically happens in a previously open blood vessel that shows signs of plaque (atherosclerosis) or other damage, or that doctors previously repaired with a stent or graft.

The artery becomes blocked in one of two ways:

• It slowly narrows to a close as plaque builds up
• Tiny networks of blood vessels in the plaqued walls of an artery tear, and the blood and fluid form a clot.

Symptoms include:

• Pain in the affected limb gets gradually worse and spreads slowly toward the trunk of your body. (DVT pain tends to center on thrombosis.)
• The skin of the limb is typically cool to the touch. (DVT typically warms the skin.)
• Skin looks pale and patchy because of lack of blood supply to the skin’s surface. (DVT typically reddens skin.)
• Skin can blister as the condition worsens. (uncommon in DVT)
• You and your doctor may not be able to feel a normal pulse in the affected limb. (uncommon in DVT)
• Burning or prickling sensation, typically in the legs, feet, hand or arms (possible, but uncommon, in DVT)

Also known as “flesh-eating disease,” it’s a life-threatening infection that spreads quickly and kills the body’s soft tissue (muscle, fat, and tissue connecting muscle to bone). Injury or surgery can create a break in the skin that may lead to infection if the right bacteria are around.

If you’re healthy, have a strong immune system you’re unlikely to get it. It’s treated with antibiotics through a vein, along with surgical removal of infected tissue. Early symptoms can include:

• An area of skin where redness, warmth, or swelling spreads quickly
• Serious pain, including beyond the skin obviously affected
• Fever (uncommon in DVT)

Later symptoms might include:

• Changes in skin color
• Blisters or black spots on skin (uncommon in DVT)
• Liquid or pus oozing from sores (uncommon in DVT)
• Tiredness, dizziness, diarrhea, or nausea

It’s a kidney illness that causes your body to pass too much protein when you pee. It’s typically due to damage to the tiny blood vessels in your kidneys (glomeruli) that filter waste and extra fluid from your blood. A number of conditions can cause this damage, including diabetic kidney disease, amyloidosis, glomerulosclerosis, and lupus. Typical symptoms include:

• Swelling from fluid buildup (edema), especially around ankles, feet, and eyes, often on both sides (instead of just one in DVT)
• Foamy urine, a result of excess protein in your urine (uncommon in DVT)
• Weight gain due to fluid retention (uncommon in DVT)
• Tiredness (uncommon in DVT)
• Loss of appetite (uncommon in DVT)

Heart failure means the heart doesn’t pump as well as it should. Congestive heart failure (CHF) is a type that happens when blood flows too slowly out of the heart. This causes a backup of the blood trying to return to the heart and lungs for more oxygen.

The pressure causes a buildup of fluid (edema) that can collect, most often in the legs and ankles, but other areas as well. CHF also could increase the work of your kidneys, which often leads to edema. The swelling could mirror DVT, but it typically happens in both legs instead of just one as in DVT.

Fluid that collects in the lungs (pulmonary edema) can cause shortness of breath that mirrors the symptoms of a pulmonary embolism that can happen with DVT. Symptoms typically worsen when you lie down.

It typically happens when doctors remove or damage one or more of your lymph nodes — small glands that help get rid of fluid, waste, and germs — as part of cancer treatment. This stops fluid from draining, and that causes arms, legs, feet, and other areas to swell. There’s no cure, but your doctor can help you manage it with movement exercises, massage, and bandages that push on swollen areas.

As with DVT, lymphedema often causes swelling or tightness in all or part of an affected limb. Also like DVT, symptoms are sometimes so mild that you don’t notice. Unlike DVT, the swelling can often include your fingers or toes. Other symptoms include:

• A feeling of heaviness in affected legs (uncommon in DVT)
• A hard time moving as freely
• A general aching or discomfort (DVT pain tends to center on a specific area)
• Infections that repeat (uncommon in DVT)
• Skin that hardens and thickens (fibrosis)

It’s when blood pools in the veins. It happens when the valves in your veins stop working properly, so the blood moves backward and collects. This pushes fluid into nearby tissue, which can cause swelling and irritation that looks like DVT. Over time, this inflammation can start to break down tissue and lead to sores or “ulcers” on the surface of the skin (uncommon in DVT).

You may feel full, achy, and tired in your legs, and it may get worse when you stand. You also might notice varicose veins on the skin of your legs.

Your muscles group together in your arm, leg, hand, or foot, along with blood vessels and nerves. Each group is enclosed in tissue (fascia), and together, they make up a “compartment.”

When the pressure builds up inside one of these compartments, it can cause swelling and tenderness that mirror symptoms of DVT. Unlike DVT, acute compartment syndrome typically happens soon after a sudden injury like a fracture. Other possible causes include a serious burn that scars skin or surgery to repair a blocked blood vessel. You may also notice:

• Tightness in affected muscle
• Intense pain, especially if you stretch muscle (more than expected for injury)
• Tingling or burning feeling
• Numbness or weakness (may be signs of permanent damage)

Acute compartment syndrome is a medical emergency and requires treatment right away.

This happens when a blood clot forms in a vein just under your skin. If you have it, you may have:

• Swelling
• Pain
• Tenderness
• Warmth
• Redness

These symptoms are much like those of DVT, but unlike a DVT, it happens close to the surface, not deep within your body.

About 20% of people who have this condition also get a blood clot in their leg. Call your doctor if you notice anything unusual. They’ll check to see what’s going on.

The child’s legs hurt.

What to do?

What is leg pain in a child?

Leg pain can be described as any sensation of pain or discomfort in the area between the groin and ankle. Depending on the cause, leg pain can range from moderate to severe, and symptoms can be constant (continuous) or intermittent (come and go). Leg pain can be acute, meaning it comes on quickly and then goes away. Or it can take weeks or months. Then it is called chronic leg pain. For some children, chronic leg pain can last for years and affect their lives.

What symptoms are associated with leg pain?

Pain in the leg may affect only a small part of the leg, or may cover most or even the entire leg. The pain may be dull or sharp, burning, tingling or dull. The child may experience pain in the buttocks, lower back, spine, or foot.

Other signs and symptoms that may occur with leg pain include:

• swelling
• varicose veins 9What causes pain in the legs of children?

  Here are some common causes of leg pain:

  • Cramp: This is when the muscles suddenly contract. The pain is usually felt in the lower leg and goes away on its own fairly quickly.
  • Muscle strains and strains. The leg may be very sensitive, and there may be muscle spasm, swelling, or difficulty moving the leg.
  • Minor injury such as a blow, blow, or bruise: There may be redness, swelling, or discoloration of the skin at the site of the injury.
  • Fracture: A broken or cracked bone can also cause swelling, deformity, bruising, and loss of strength or movement in the leg.
  • Infection: Ulcers, infected wounds, or blisters may also cause redness, swelling, and fever in the affected area. The child may have a fever and general malaise.
  • Injury to nearby joints, bones, or muscles: Very painful nodules can form in surrounding muscles, ligaments, and tendons. Pain in the back of the leg can be caused by back joint problems or sciatica. Ankle, knee, or hip problems can also cause leg pain.
  • Too little use of the leg: The child may also have tingling or muscle stiffness.
  • Blood vessel problems such as blood clots (deep vein thrombosis) or poor circulation: The child may also have swelling, pressure, tenderness, or paleness in the legs.
  • Varicose veins: the pain may be aching, throbbing or burning. The child may also have heaviness, cramps or restlessness in the legs, swelling of the ankles, darkening of the skin over the veins, and an itchy rash.
  • Nerve problems such as diabetic neuropathy: The child may also have weakness, numbness or tingling.

  Growing pains in children

  Pain in the legs is very common in children, especially at primary school age. Most often, such pains are “growing pains”. It is not known what causes growing pains. In most children examined by doctors with growing pains, there is no objective reason for their appearance. One theory is that pain is related to exercise, but this is not always the case. Some children with growing pains in their legs may also experience abdominal pain and headaches. In these children, growing pains may be associated with stress or anxiety and may be psychosomatic.

  Symptoms of growing pains in the legs

  If your child has growing pains, he may say that he has aching or burning sensations in both legs – in the muscles of the thighs, calves or feet. Pain can also occur in the arms or other parts of the body, although this is much less common. Pain in the legs usually occurs at night and can sometimes even wake the child. They are also common during the daytime, but are rarely dangerous enough to interfere with daily activities. For most children, leg pain or discomfort tends to come and go. It is difficult to say when such pains will begin and when they will pass. A child with growing pains in the legs usually starts on their own or allows the parents to massage the painful area. This can help tell the difference between growing pains and a more serious condition. Children who have leg pain due to a more serious cause usually do not allow anyone to touch the painful area.

  Should I see a doctor about my child’s leg pain?

  You should take your child to a GP if you think something more serious is going on with their legs. For example:

  • The pain is very severe and does not go away.
  • Your child is lame.
  • Painful part of the body is sensitive, hot or swollen to the touch.

  Sometimes your GP may order an x-ray or blood test to make sure there is no other cause of pain, such as a fracture or inflammation.
