How to Tell If You Have a Blood Clot in Your Leg

In deep vein thrombosis (DVT), blood clots form in the deep vein in the leg calf. The danger with clots in the legs occurs when a clot moves out of the leg and into the lung, forming a pulmonary embolism. DVT commonly occurs after extended periods of immobility, such as a stay in the hospital or a long airplane flight. In roughly half of the cases, DVT occurs without any noticeable symptoms, but if you notice signs of DVT you should call your doctor as soon as possible.

Instructions

1. Take notice of any swelling in your leg, including your foot and ankle. This could be a sign of a blood clot. The clot can restrict blood flow, causing the blood to build up and cause swelling.

2. Note any pain in your legs, particularly your calf. The pain usually begins in your calf and can feel like a cramp. The pain can move into your ankles and feet.

3. Look for any redness and warmth on the area where you suspect a blood clot.

Tips & Warnings

• The following can increase your chances of DVT: pregnancy; taking an oral contraceptive; smoking; heart failure; family history of DVT; and being overweight.
