Hello. I have a series of rashes that have broken out on my body. It started off with one just above my left knee and one surrounding my right knee. Then I developed one on my left shin, right ankle, stomach, two huge ones diagonally across my shoulder blades, one on my chest and one on my left arm. They are very bright red and are uncomfortable and much warmer than the rest of my skin. They either becomes faint or disappear completely by night, then return during the day. Most of them have gone away over the last two weeks, now I just have the one on my chest and the one on my left arm. Is this something I should be concerned with?
