hello. for a few months now I have had almost constant all-over body itching. It subsides every now and then but usually just for a few hours. Lately though, it has gotten worse and tiny bumps have been appearing when i scratch. it is on both my arms, on the sides of my back, and my chest and abdomen. i have a lot of stretch marks though and they itch alot anyways but since ive been scratching more than ever today, the tiny bumps started appearing everyhwere i scratched. but they soon get smaller and ALMOST disappear when i stop scratching for a while. but the problem is i cant stop...im so darn itchy. it feels a bit like a heat rash and the bumps only get red when i scratch or wen i get hot. i havent had any flu-like symptoms and i havent vomited and no sore throat or anything like that. i have muscle aches at times but alot of that is female problems. I think im making myself more nervous worrying about this rash as being an HIV indicator but im too scared to get tested. i mean besides a rash, i dont have any other symptoms. My dad thinks me worrying and scratching is making my rash worse. do you think its possible that i have HIV ? also, could it be possible that i have eczema? thank you so much for your time.
