I just realized that I have a rash on my lower abdomen. Mainly from just above my navel to about my underwear line. Not painful, not very itchy - red, raised fairly large bumps, generally in clusters. It extends up the right side of my torso as well, but there s nothing on my left torso. They look quite angrily red, but are not actually causing discomfort. Should I be worried / go see a doctor?
