Deep vein thrombosis can have the same symptoms as many other health problems. But about half the time, this blood clot in a deep vein, often in your leg, causes no symptoms.

If you're over 60, you smoke, you're overweight, or you sit for long periods of time, your risk for the condition is higher, so stay alert for signs of a problem. Talk to your doctor right away if you think you might have DVT.

Call your doctor right away if you have these DVT symptoms, especially if they appear suddenly:

  • Swelling in one or both legs
  • Pain or tenderness in your leg, ankle, foot, or arm. It might feel like a cramp or charley horse that you can’t get rid of. Leg and foot pain might happen only when you stand or walk.
  • Warm skin on your leg
  • Red or discolored skin on your leg
  • Veins that are swollen, red, hard, or tender to the touch that you can see

Call 911 or go to an emergency room right away if you notice leg pain or swelling and:

  • Sudden coughing, which may bring up blood
  • Sharp chest pain or chest tightness
  • Pain in your shoulder, arm, back, or jaw
  • Rapid breathing or shortness of breath
  • Pain when you breathe
  • Severe lightheadedness
  • Fast heartbeat

If you have a blood clot and it breaks free, it could travel to your lungs. That's called a pulmonary embolism, and it can be deadly. Like DVT, it may not cause symptoms.
