When can blood clotting be a problem?
Sometimes blood clots form abnormally within a blood vessel. In some cases the clot becomes large enough to block the blood flow.
The medical term for development of an abnormal blood clot is thrombosis.
Sometimes all or part of a blood clot breaks off and travels to other parts of the body. This is called an embolism.
