Post-thrombotic syndrome is a condition that can happen to people who have had a deep vein thrombosis (DVT) of the leg. DVT occurs when a blood clot 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.

You can get DVT if you have certain medical conditions that affect how your blood clots. A blood clot in your legs can also happen if you don't move for a long time, such as after you have surgery or an accident, when you're traveling a long distance or when you're on bed rest.


In some cases, post-thrombotic syndrome causes only a few mild symptoms. In other cases, it can cause severe symptoms. The symptoms occur in the same leg that had the DVT, and can include:

  • A feeling of heaviness in the leg
  • Itching, tingling or cramping in your leg
  • Leg pain that’s worse with standing, better after resting or raising your leg
  • Widening of leg veins
  • Swelling in your leg
  • Darkening or redness of the skin around your leg

Risk Factors

Certain factors may increase your risk for post-thrombotic syndrome, such as:

  • Obesity
  • Having a DVT that causes symptoms
  • Having more than one DVT
  • Increased pressure in the veins in your legs
  • Getting a thrombosis above the knee instead of below it
