basically I got my belly button pierced last year on the 11th of May and for 7 months it had this red thing which looked like a buble of blood/skin ( what I have now in the pic) and then I went to a piercing shop and they said that it wasn't infected and it was just reacting to the metal, so I ended up buying a titanium metal bar and literally the next day it started to heal and that buble thing just ended up disappearing but now all the sudden it appeared again and I have a few spots around it too... any thoughts what this might be?
