so Thursday morning i got out of the shower and noticed my legs and elbows were a little itchy. so i scratched them a little and thought nothing about it. well an hour later i had hives all over my knees and elbows. so i went to urgent care and he said its an allergic reaction to something so he gave me some prednisone and sent me on my way. now the steroids seem to work a little but I'm also taking benedryl cream and a pill. i itch almost all the time and its not just those spots. its literally everywhere but my face. I've been on the steroids for 3 days not and doesn't seem to be an end in sight. i plan on making an appointment for my regular doctor tomorrow. but is there anything i can do until then? any ideas what would cause this? I'm miserable over here so any help would be appreciated
