Purple nipples??

Veronica

So I had my nipples pierced for about a year and a half and had so many problems with my left one healing. That one eventually just fell out one day maybe a month or two months ago and I haven’t seen it since. The hole is closing. I look in the mirror this morning and it’s a deep purple. Like a bruise color purple and they’ve been hurting so bad. What does this mean???😭
