How To Tell If It's A Blood Clot: Signs, Symptoms And More

When blood clots form inside the veins, they do not always dissolve on their own. Immobile blood clots are usually harmless, but they can become dangerous if they break free. A blood clot can travel to the heart or lungs, which is life-threatening. According to the American Society of Hematology, nearly 900,000 Americans develop deep vein thrombosis each year. It is impossible for one to know if he or she has a blood clot without proper medical guidance, but those who know what symptoms to look out for can seek medical attention quickly.

Arms and Legs

Most blood clots occur in the lower legs and typically form when an individual is inactive for a lengthy period of time. For example, a blood clot may develop in a patient's leg after spending hours cramped on a plane. The symptoms experienced vary based on the size of the clot; bigger clots are usually more painful than smaller-sized ones. Those who have a blood clot in their arm or leg are likely to experience swelling and tenderness. If the clot is small, minor calf swelling can also occur, whereas bigger blood clots can cause the whole leg or arm to swell. Those who have a clot may notice a warm sensation or the affected area may turn bluish in color.
