I searched and know people have asked questions before but I thought maybe someone could identify what caused some rashes on my body if I described them. I first noticed it on the back of my upper left arm and thought it was just blemishes or ingrown hairs. It seems to have spread down to my elbow area and I noticed a patch on my leg. The 'rash' is raised bumps which resemble blemishes. They itch sometimes and get more red if I touch the skin around them. I'm including pics but the camera didn't pick up the details very well. The first picture is of my arm and leg side by side and the second is just of my leg.
