I was talking to someone about HIV rashes, and they said that the common rash from HIV is usually located on the upper back, chest, or the whole body. Is this true? and is it possible to just get the rashes on your thighs? The reason I ask is because I have been getting itchy skin irritation rashes on my thighs that only last for a day and then disappear and come back a week or 2 later. I have been to the doctor, and he doesn't know exactly what they could be because I didn't have any when I went in. Does this sound like anything to anyone?
