Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but also can occur with no symptoms.

Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. It can also happen if you don’t move for a long time, such as after surgery or an accident, or when you’re confined to bed.

Deep vein thrombosis signs and symptoms can include:

Swelling in the affected leg. Rarely, there’s swelling in both legs.

Pain in your leg. The pain often starts in your calf and can feel like cramping or soreness.
Red or discolored skin on the leg.
A feeling of warmth in the affected leg.
Deep vein thrombosis can occur without noticeable symptoms.

When to see a doctor

If you develop signs or symptoms of deep vein thrombosis, contact your doctor.

If you develop signs or symptoms of a pulmonary embolism — a life-threatening complication of deep vein thrombosis — seek immediate medical attention.

The warning signs and symptoms of a pulmonary embolism include:

Sudden shortness of breath
Chest pain or discomfort that worsens when you take a deep breath or when you cough
Feeling lightheaded or dizzy, or fainting
Rapid pulse
Coughing up blood
