I have I rash on my lower right leg. It is a bunch of red raised spots that form a round spot about the size of a gold dollar, its also warm to the touch. I also have a bunch of red spots all over both legs. Both legs are really itchy.

Could it be because I have sciatica, 3 bulging disk, and a herniated disk
