I recently developed red rash like circles all over by upper thighs but originated from just one rash on my lower buttocks. They are not raised(flush with the skin), itch, hurt or swell, they have bled before though. They vary in shape size and intensity of redness. And are continuing to multiply and it has already been over a month since the first rash developed. And non seem to go away or lessen in size or redness.
