Bone bruises, also known as contusions, are the result of direct or repeated blows from an object or person. This type of injury may be caused by falls, automobile accidents, sports injuries or slamming the body against a hard surface. The result is a swollen lump that forms over the injured site due to bleeding beneath the skin. Other symptoms include pain, stiff muscles and limited range of motion. Treatment involves the RICE (rest, ice, compression and elevation) method along with pain medications.
Microscopic vessels with walls no thicker than single cells, capillaries often burst, spilling their contents. Your body, although lacking flood insurance, responds routinely and effectively.
Everyone has gotten a bruise under his skin at one time or another, whether from something as simple as accidentally hitting your hand against a piece of furniture or the result of a serious accident. Self-treatment for what medical professionals call a contusion is fairly straightforward and can be done in the comfort of your home.
