Discoloration caused by a bruise

Answer 1

A bruise is in medicine called a contusion. A bruise occurs when force injures the small blood vessels, capillaries. Blood leaks out of capillaries into the tissue. This initially causes the skin to turn a dark black or blue or some mixture. This deep, dark coloring signifies the bruise is fresh or new. But the body immediately begins repairs. Macrophages zoom to the area to do clean up, which causes heat at the site, so a bruise might feel warmer than regular skin. The circulatory system sends in more blood flow to promote healing. As macrophages eat up debris, and the body reabsorbs blood/debris from the tissue, the bruise begins to change to a rainbow of colors: blue, green, yellow, pink, etc. These colors begin to lighten into pastels. When you see a multicolored bruise that looks like it is spreading or getting bigger, and multi-colored or pastel, it is a sign of an old bruise, not new. Within 7-10 days the body has done much of the work, and the bruise has faded or healed.
