Blood clot formation. Overview. Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

These knots can range from the size of a pinhead in smaller muscles to the size of your thumb in larger muscles.o treat the muscle knot, simply roll the massage ball pressed either to the wall or the floor one side, and your body on the other over your muscle.
