How can you tell if a blood clot is forming in your arms and legs?

ANSWER

When a blood clot forms in one of the deep veins in your arm or leg, way beneath your skin's surface, it could be something called a deep vein thrombosis (DVT). That's dangerous because the clot could travel to your heart or lungs. You're more likely to get DVT if you haven't moved around for a long time, say after surgery or during a long plane trip. Get medical help right away if you notice any of these symptoms:

  • Swelling.
  • Change in color.
  • Pain.
  • Trouble breathing.
