A blood clot in the leg, is called deep vein thrombosis. If you even suspect you have a blood clot, you need to see a Dr. ASAP!! The clot can travel to the lung and cause a pulmonary embolism. I copied the symptoms of a blood clot:
Symptoms occur in the affected leg when a clot obstructs blood flow and causes inflammation. Symptoms may include the following:
* Swelling
* Gradual onset of pain
* Redness
* Warmth to the touch
* Worsening leg pain when bending the foot
* Leg cramps, especially at night
* Bluish or whitish discoloration of skin
*However, almost 30%-50% of individuals with deep vein thrombosis do not experience symptoms from the condition.
