ive had my belly button pierced for almost a year, and recently its become red, crusty, and i can see the bar through the skin. Is it rejecting? Infected? i went back to my piercer afew weeks ago, she said it was because i changed the bar, i put my old one back in, but it fell out and i lost it, so i baught a new one, stainless steel like my original one, and now it looks awful. Its just the top hole thats all crusty and red. Sometimes it weeps puss, its generally just awful. Do you know what it could be? rejection, infection or something else? Thanks for reading.
