It began right below the groin and was red swollen dry scaly and extremely itchy. it went away after about a week and a half but now i have small severly itchy bumps all over my arms,legs, groin,stomache,and blister looking bumps on the palms of my hands. hydrocortizone is not helping either. Can this be a hiv sympthom because I had an unprotected sex about a month ago...pleasehelp.
