It is important to recognize the signs of a blood clot in the leg, because the condition can be dangerous and even deadly if the blood clot travels to the lungs. The most common signs of a blood clot in the leg include pain in the area around the blood clot, redness, swelling and warmth in the limb that is affected. Additionally, the victim of a such a clot may experience leg cramps or increased pain when stretching the calf. Some people never experience these symptoms, however, which is what makes this condition especially dangerous.

A blood clot in the leg is known as deep vein thrombosis, or DVT, and it can occur for a number of reasons. Trauma to the area, such as a severe bruise or broken bone, is one of the most common causes, though some people are simply more prone to blood clotting problems. Recent surgical procedures may also cause blood clots to form, as well as remaining in bed or sitting in a chair for prolonged periods of time. The most common signs of a blood clot in the leg include pain and swelling, so if these symptoms occur, it is necessary to visit a doctor who can discuss various treatment methods such as anticoagulant medications.

Skin discoloration is another one of the signs of a blood clot in the leg. Some people will simply notice that the area appears more red than the surrounding skin, as with any injury to the skin. Others will notice that the skin has a blue or white appearance to it. In addition, the skin might feel warm when it is touched, as compared to the surrounding skin or the other leg, which should not feel as warm. It may become painful to walk, and especially unpleasant to stretch the calf, which is one of the more common locations for blood clots.

These signs of a blood clot in the leg are easy to miss, but it is important to be vigilant, especially after any trauma to the leg that makes a clot more likely. If the clot is not treated and it travels to the lung, it can cause a pulmonary embolism or other serious issues that can lead to death. Shortness of breath, dizziness, fainting, or chest pain should always be treated as an emergency, as these can also be signs that the blood clot has traveled to the lungs or heart.
