Answer:
When a wound swells up, turns red and hurts, it may be a sign of inflammation. Very generally speaking, inflammation is the body's immune system's response to an irritant.
Immediately following an injury, the traumatized area becomes red, warm, and painful, and it begins to swell. The swelling process, also known as edema, is the result of acute inflammation, a response triggered by damage to living tissues.
Redness is caused by the dilation of small blood vessels in the area of injury. Heat results from increased blood flow through the area and is experienced only in peripheral parts of the body such as the skin.
