I have a rash that starts off as small red bumps. In a day, it is the size of a half dollar and so so itchy. It is not scaly, only slightly raised and the center is a brighter red then the rest. It's mainly on my arms by the wrists, elbows and the fleshier part on my upper arm although at first I did have some by my knees and ankles...so itchy. Please help!!!
