Don't see red over inflammation
Inflammation is one of the most common causes of body pain. When tissues in your body are damaged, tiny blood vessels (capillaries) leak blood cells and plasma into the area. Damaged tissues also release chemicals that stimulate pain receptors and increase blood supply to the area. These processes cause swelling and redness and can make the area warm to the touch. The swelling also places pressure on nerves, adding to the pain.
