Symptoms of deep vein thrombosis -- a blood clot in a deep vein -- may be difficult to identify. That's because DVT symptoms are similar to many other health problems.
If you're at risk for DVT -- you are over 60, you smoke, you are overweight, you sit for long periods of time -- stay alert to DVT symptoms. If you have symptoms, learn what you can do to confirm a diagnosis.

That's because the blood clot, which usually forms in a calf or thigh deep veins, can partially or completely block blood flow back to the heart and cause damage to the one-way valves in the veins. The clot can also break free and travel through your blood to major organs, such as your lungs -- which...
DVT is the formation of a blood clot in a deep vein, usually in a calf or thigh muscle. DVT can partly or completely block blood flow, causing chronic pain and swelling. It may damage valves in blood vessels, making it difficult for you to get around. A blood clot can also break free and travel through your blood to major organs, such as your lungs or heart.
