Sorry if this is the wrong category to ask this question, but any help is appreciated.
I recently noticed a lot of small bumps all over my upper back/chest/shoulder and even parts of my stomach. Ive never had this before and it just seemed to appear out of no where. I have the feeling its KP but Ive never experienced anything similar to this. Ive also had a very severe sun burn in the same area before, but that was almost a year ago, its also slightly itchy now and then. Im a 15 year old male if thats of any help. Please help?
