If you have a blood clot in leg would you notice the symptoms?

Usually: Pain, swelling, redness, bulging veins, possibly fever. If any doubt, have it checked out. If you are active at your age, this would be a rare occurrence in the absence of trauma or circulatory disease.

Sometimes: About half of all DVT cases do not cause symptoms. The symptoms you feel can depend on the location and size of clot . They include swelling, tenderness, leg pain that may worsen when you walk or stand, sensation of warmth, and skin that turns red or blue. If you and your doctor are concerned a good history and ultrasound is indicated. This is a noninvasive test that will provide the diagnosis.
