You step in a hole and turn your ankle, or tweak your knee. You throw too much and feel a twinge in your shoulder. You try to break your fall with your wrist. Acute injuries are easy to recognize: first comes the pain, and then comes the swelling. Chronic, or long term injuries, take weeks, sometimes even months, to develop, but it is the same story: first comes the pain, and then comes the swelling.
Swelling is a normal reaction of the body to an injury. In general, it is any abnormal enlargement of a body part. This can be due to fluid – including blood – bony malformation, muscle, or any number of things. Sometimes, though, the body goes overboard, and the inflammatory response is excessive and can actually begin to cause more damage than good.
