Knowing the symptoms of a venous thrombosis is the most important step in treating a blood clot when it occurs. Often people do not know or recognize the symptoms, but think they are having ordinary leg pain or a cramp.

When a blood clot forms, it can partially or completely block the blood flow in the vein. This is what causes the symptoms.
