for the past few months i have had 2 small, red bumps on my arm. they were small and weren't very itchy at first but recently they have been itching a lot and for the past month or so the spots have been spreading. it went to the side of my arm/elbow, then to my sides, then to my thighs, and just today another spot appeared on my shoulder. the spots are all the same, a tiny cluster of dots within a cm radius. if i itch them to the point where the skin comes off there are tiny red dots but they don't bleed.
i am prone to getting strange skin problems. doctor said i had some diagnosed thing saying that my skin is overly sensitive. i cant remember the acronym but i remember it sounded like ATP when i heard it but she corrected me. the rash has been here for around two months and from even before then i hadn't switched any of my products or anything. it itches the same amount morning noon and night so i don't believe it's scabies and i was recently tested so i know it's not std related. below are some images, thanks.
