hi, for the last few months i've had some discolored spots appearing on my neck nad shoulders, they don't bother me too much, however they only started out small only a couple on my neck now it goes down my neck nad on my shoulder and now its on the other side they sometimes dry out and get a little itchy but not too bad. a friend of mine says they kind of look like psorisis or exezema, is it possible to get these when i've never had them until now? i've been using over the counter hydrocortizone for it it helps with the dryness but it doesn't get rid of them, any ideas or what it could be and what i could get to help it?
