Super Hot Guy	Who knows Was this answer helpful to you? Yes / No

Bette	Probably dermatitis. Just a topical bacterial infection caused lots of time by unknown bacteria or an allergic reaction to something. Go ask a pharmacist to recommend an over the counter cream and try it before you spend the money on a doctor. If it is not extremely painful, it is probably not serious. Was this answer helpful to you? Yes / No

Heartßroken for another day	Well i really don't know what it is but it might be dry Skin which often appears during the winter time. My advise if you have this is to put lotion on that spot usually when you are just about to sleep. It really helps. It also might be that you are allergic try finding out that particular item that is causing you to have this and ask your doctor about what you should do. It could also be these rashes that usually go away several weeks later. But if its not I suggest asking a Doctor to see what might be the problem and to not scratch,scratching never helps even though you can't resist. Good luck:) Was this answer helpful to you? Yes / No

Steven	The only thing that comes to mind for me would be reaction to deodorant but that unlikely would cause any problem on the top of you shoulder. Bottom line: If it doesn't go away, see a doctor or "doc in a box" at your local drug store. Was this answer helpful to you? Yes / No

toe poe gee gee oh	Not even a doctor can diagnose this rash without seeing it or taking a scraping for a culture. If it is spreading , I would be worried that it would get on my face. It is probably your normal bacteria , out of control in this area and you need a cream like Bactroban. YOu have to go to the doctor. Was this answer helpful to you? Yes / No

Dave B	ask doctor on phone Was this answer helpful to you? Yes / No

cheesey thug	a lot of things could be wrong that start with a rash, however because of the fact that you have had it 3 weeks with no other symptoms i would have to say that you simply brushed some poison Ivy, or some other non serious reason. If you get any other side effects or if the rash doesn't go away within a month or so, see a doctor Was this answer helpful to you? Yes / No
