Document Summary
Increased temperature - is the result of an increase in blood flow to the injured area due to damaged blood vessels and the need to supply the area with an increased number of white blood cells. Much as the body develops a generalized fever when ill, an injury to a soft tissue of the body causes a local fever. this is why heat, hot packs or hot soaks are not used on a new injury. Redness- is due to the increase in blood flow to the area. Swelling- also is due to the increase in blood flow to the area. Additionally, damage to the cells, small capillaries and lymphatic vessels in the area may allow the leaking of some fluid. Pain- is often due to pressure on nerve endings from increased swelling. Loss of function- is caused by swelling in the area and guarding of the muscles surrounding the injury.
