Blood clots, on the other hand, can occur for a number of reasons.
Sometimes this is part of the natural process of healing after an injury.
Medical News Today states: “Damage to an area causes coagulants in the blood called platelets to collect and clump together near the injury, which helps stop the bleeding. Blood can also clot without any apparent cause.
“Small clots that form may disappear on their own. However, some blood clots become larger than necessary or form in places where there is no injury.”
Unlike bruises, blood clots do not necessarily follow an exact pattern as they heal and can become far more serious.
