hey guys, ive been having this super itchy arm rash for about a month now, first it started as super really small itcht bumps that werent realyl red, then after a while of itching my skin color changed i dont know if its peeling that thats new skin but i havent seen any loose skin on my arms and sometimes its very itchy but then it goes away so far nothing seems to work the doctor gave me this ointment that doesnt work, cortisone cream doesnt work i dunno wat to do please help me !!!! here are some picks, also i got this about the same time i got really bad sunburn on my face and that hasnt healed either, aloe vera doesnt work on the sunburn but neosporin seems to help i dunno but back to my arms yeah my theory is it is heat rash or it could be an alergic reasction but ive never been alergic to anything i juss need some advice
