A couple of years ago I noticed a brownish spot appeared next to my belly button. A friend told me it was probably just an age spot / liver mark (although I am 20). Yesterday, I noticed it was flaking off and itchy. Today, it looks like this. Reddish but white in the middle. I'm really concerned and have been anxious over this since last night. Does anyone know what this could be?? (The redness around my navel has been there for a while too.)
