Key Takeaways

Sock marks from tight socks or long periods of sitting or standing are usually harmless, but deep, frequent, or slow-to-fade indentations may point to fluid buildup in the lower legs, a condition called peripheral edema.

View all takeaways

Do you ever take off your socks and notice deep indentations on your legs? Most sock marks are harmless, especially when they happen after you wear tight socks or sit or stand for a long time.

But when sock marks are deep, frequent, or slow to fade, they may point to fluid buildup in the lower legs. That swelling can have many causes, including heart failure, kidney disease, liver disease, vein problems, or certain medications.

In this article, we’ll discuss why socks leave indentations on legs, when sock marks may signal a health concern, and when to seek medical advice.

🗳️ Have you noticed sock marks or leg swelling with heart disease?

Yes, I have.

No, I haven’t.

I’m not sure.

Why Socks Leave Indentations on Your Legs

Sock marks are indentations on your skin caused by pressure. They may be more noticeable when extra fluid collects in the lower legs and causes swelling. This is called peripheral edema.

Minor sock marks or leg swelling tend to be normal if they occur because of:

Tight socks — Elastic bands or tight-fitting fabric can press into the skin and leave temporary indentations.
Prolonged sitting or standing — Sitting or standing for a long time can make fluid collect in your legs and feet.

When sock marks occur due to swelling, it can cause pitting. Pitting means that when pressure is applied to the skin, it leaves a dent. When the pressure is removed, the dent slowly goes away.

Mild, occasional sock marks usually aren’t a concern. Sometimes, however, severe sock marks that last a while can indicate an underlying health issue.

How Long Should It Take for Sock Marks To Go Away?

There isn’t one exact time that applies to everyone. Mild swelling often improves on its own, especially after you rest, move around, or raise your legs.

If swelling lasts a few days, happens often, and doesn’t seem to be getting better, contact your healthcare provider. New swelling is worth discussing because a care team can look for possible causes.

Are Sock Marks Related to Heart Disease?

Sock marks aren’t a typical sign of heart disease. However, they can happen when leg swelling is related to heart failure.

When the heart doesn’t pump with enough force, blood can back up in the veins and push fluid into body tissues, causing swelling. This swelling can occur in the legs, feet, ankles, stomach, fingers, and elsewhere in the body.

Many members of MyHeartDiseaseTeam experience extreme leg swelling. “I have excessive edema in my feet and legs even after taking diuretics,” one member said.

What Other Conditions Cause Sock Marks?

Apart from heart failure, there are other conditions linked with lower-leg swelling:

Kidney problems — Leg swelling can happen when the kidneys have trouble managing fluid in the body.
Liver scarring — Cirrhosis (scarring in the liver) can be linked with swelling from fluid buildup.
Chronic venous insufficiency — This vein problem can make it harder for blood to move from the legs back to the heart.

Does a Heart Attack Cause Sock Marks on Legs?

Sock marks are not a typical heart attack symptom. Chest pain is usually the most common symptom. Emergency care is needed if you think you may be having a heart attack.

When Should You Be Worried About Sock Marks?

A painful, swollen, discolored leg can suggest deep vein thrombosis (DVT), a blood clot that forms in a vein, usually in the legs. DVT needs an urgent medical evaluation.

If you have leg swelling, watch for these symptoms of DVT in your leg:

Swelling in one leg
Warmth or pain
Large veins
Skin color changes

Severe, frequent, or long-lasting sock marks may indicate a more serious issue. Speak with your doctor to find out what’s causing your symptoms.

Can Medications Cause Sock Marks?

Some medications can cause leg swelling, which may make sock marks more noticeable. These include some drugs used for diabetes and high blood pressure.

The following medications can cause or worsen swelling:

Calcium channel blockers, such as amlodipine, felodipine, and nifedipine

Some pain relievers, such as ibuprofen or naproxen

Hormone therapy

Some diabetes medications

If you notice new or worsening swelling after starting or changing a medication, tell your healthcare provider. Don’t stop or change a prescribed medication unless your healthcare provider tells you to do so.

Lifestyle Changes To Manage Leg Swelling

You can try at-home strategies to help manage mild leg swelling. Talk to your healthcare provider for a plan that fits your needs.

Adjust Your Position

If you notice sock marks at the end of a long day, especially after standing or sitting, try elevating your legs. Raising your legs above your heart while sitting can help blood flow back to your heart.

Taking breaks from one position may also help. Walking around can help increase blood flow to your legs.

Try Compression Socks

Many MyHeartDiseaseTeam members also use compression stockings to help with swelling. One member shared, “Compression socks help to reduce my swelling, but they feel so bloody tight! Definitely gonna have to get used to this.”

Ask your healthcare provider before using compression stockings, especially if you have poor circulation or peripheral artery disease. For some people, compression stockings could make symptoms worse.

Switch to a Low-Sodium Diet

A lower-sodium diet may help some people with fluid-related swelling. Talk with your healthcare provider before making major diet changes.

Other Symptoms To Look Out For

Seek medical advice if you notice sock marks with any of these symptoms:

Unexplained weight gain — Sudden weight gain can be a sign of heart failure or worsening heart failure.
Breathlessness — Shortness of breath during activity, while resting, or when lying down can be a symptom of heart failure.
Worsening swelling — New or worsening swelling in the legs, feet, ankles, or abdomen should be reported to your healthcare team.
One-sided pain or discolored skin — Swelling in one leg that is painful, warm, or discolored may be due to a blood clot and needs urgent evaluation.

If you have heart failure, report sudden changes to your healthcare team.

Your doctor can help determine whether your symptoms are related to heart disease or heart failure, medication side effects, or another condition.
