Understanding what a blood clot feels like and recognizing the associated symptoms is crucial for early detection and prompt medical intervention. Blood clots can have serious consequences, including heart attacks, strokes, and pulmonary embolisms, so it's essential to be vigilant, especially if you have risk factors or a family history of blood clots.

Blood clots are relatively common and form whenever we get a superficial cut, scrape, or bruise on our skin. Other kinds of blood clots can also have serious consequences if they cause a blockage affecting the heart, lungs, and other organs. According to Yale Medicine, blood clots are usually harmless; however, when blood clots form within blood vessels and obstruct blood flow (a condition called thrombosis), they can be deadly.

Understanding what a blood clot feels like is essential because early detection and medical intervention can be lifesaving. Let’s explore the signs, symptoms, and risk factors associated with blood clots so you can take charge of your health and well-being regarding this potentially life-threatening condition.

What is a blood clot?

A blood clot is a gel-like mass that forms when the blood thickens and clumps together. This natural process is crucial for stopping bleeding when you have a cut or injury, but it can be problematic when a clot forms inappropriately inside a blood vessel.

There are two main types of blood clots:

  1. Arterial clots: These clots occur in the arteries responsible for carrying oxygen-rich blood from the heart to the body's tissues. Arterial clots are usually composed of platelets and fibrin, and they can lead to heart attacks, strokes, or other organ damage.
  2. Venous clots: These clots develop in the veins responsible for returning blood to the heart. Venous clots are typically made of fibrin and red blood cells and are associated with conditions like deep vein thrombosis (DVT) or pulmonary embolism (PE).

What does a blood clot feel like?

Blood clots can manifest with a range of symptoms, and how intensely one feels a blood clot depends on factors such as the size, type, and location of the clot. Here are common sensations associated with blood clots:

  • Pain or discomfort: Many people describe the feeling of a blood clot as pain or discomfort in the affected area. This can be a sharp, stabbing pain or a dull ache, and it often worsens with movement.
  • Swelling: Clots can cause swelling in the affected limb or area, which can be significant and often accompanied by warmth and redness.
  • Skin changes: In the case of venous clots, the skin over the affected area may become discolored, taking on a reddish or bluish hue. It can also feel warm to the touch.
  • Vein hardening: When a blood clot forms in a vein, the vein itself may become firm and palpable. It can often be felt as a cord-like structure under the skin.
  • Numbness or tingling: Some individuals may experience numbness, tingling, or a pins-and-needles sensation in the area with a blood clot.
  • Localized tenderness: If you touch or press on the area with a blood clot, it may be tender or painful to the touch.

It's important to note that while these are common signs of blood clots, they can vary in intensity, and some individuals may not experience any symptoms at all.

Common locations for blood clots

Blood clots can occur in various parts of the body. Some common locations for blood clots include:

  1. Deep vein thrombosis (DVT): These blood clots form in the deep veins of the legs, thighs, or pelvis. DVT is characterized by pain, swelling, and warmth in the affected leg.
  2. Pulmonary embolism (PE): A PE blood clot occurs when a blood clot travels from the leg or another part of the body and lodges in the lungs. Symptoms include sudden shortness of breath, chest pain, and a rapid heart rate.
  3. Coronary arteries: A blood clot in the coronary arteries can cause a heart attack. Symptoms include severe chest pain or discomfort, shortness of breath, and pain radiating to the left arm or jaw.
  4. Carotid arteries: A blood clot in the carotid arteries can lead to a stroke. Symptoms may include sudden weakness or numbness in the face, arm, or leg, particularly on one side of the body, difficulty speaking, and loss of coordination.
  5. Abdominal area: Clots can also form in the veins of the abdomen. Symptoms may include severe abdominal pain, nausea, vomiting, and diarrhea.

When to seek medical help for a blood clot

If you suspect you have a blood clot or experience any symptoms associated with blood clots, it's crucial to seek medical help promptly. Early diagnosis and treatment are essential for preventing complications. Here's when to seek immediate medical attention:

Sudden severe symptoms:

If you experience sudden and severe symptoms such as chest pain, difficulty breathing, or loss of consciousness, call 911 or go to the nearest emergency room.

Symptoms persist or worsen:

If you notice any common symptoms of blood clots (pain, swelling, skin changes, numbness) that persist or worsen, contact your healthcare provider.

History of clots or risk factors:

If you have a history of blood clots or known risk factors (e.g., family history, recent surgery, prolonged immobility), consult your healthcare provider.


If you are taking medications for a known clotting disorder or are on anticoagulants (blood thinners), and you experience new or unusual symptoms, seek medical advice.

Remember that blood clots can be life-threatening, and early intervention is essential. That’s why Center for Vein Restoration (CVR) offers a same-day DVT-rule-out service. Our hotline is 877-SCAN-DVT (877-722-6388).

Risk factors for blood clots

Several factors increase the risk of developing blood clots. These risk factors can be grouped into the following categories:

  1. Medical conditions:
    • Previous history of blood clots
    • Cancer
    • Heart disease
    • Inflammatory conditions
    • Varicose veins
  2. Lifestyle and environmental factors:
    • Prolonged immobility (e.g., long flights, bed rest)
    • Smoking
    • Obesity
    • Dehydration
  3. Genetic and hereditary factors:
    • Family history of blood clots
    • Inherited clotting disorders
  4. Medications and hormones:
    • Birth control pills
    • Hormone replacement therapy
    • Some cancer treatments
    • Blood-thinning medications
  5. Surgery and trauma:
    • Recent surgeries, especially orthopedic or major surgeries
    • Trauma or injury
  6. Pregnancy and postpartum:
    • Pregnancy
    • Postpartum period
  7. Age:
    • Risk increases with age, especially over 60.

How to prevent a blood clot

While not all risk factors can be controlled, there are steps you can take to reduce your risk of developing blood clots:

  1. Stay active: Regular physical activity can help improve blood flow and reduce the risk of clot formation.
  2. Maintain a healthy weight: Obesity is a significant risk factor for blood clots, so aim to achieve and maintain a healthy weight.
  3. Stay hydrated: Drink enough water to prevent dehydration. Dehydration can make the blood thicker and more prone to clotting.
  4. Quit smoking: Smoking increases the risk of clot formation, so quitting can significantly reduce this risk.
  5. Manage underlying conditions: If you have medical conditions like heart disease or cancer, work closely with your healthcare provider to manage them effectively.
  6. Know your family history: Be aware of your genetic background and any inherited clotting disorders, as these can inform your preventive strategies.
  7. Discuss medications: If you are on drugs or hormonal therapies that increase clot risk, discuss potential alternatives or additional preventive measures with your healthcare provider.
