Nipple piercings not healing well

Ca

I got my nipples pierced Aug 30th & till about a week ago healing was going pretty well. Now I have a fairly good size bump on my left nipple, the right side of the piercing. And another small bump on my right. I totally don’t want to have to take them out 😭 I called the piercer and he said to start using tea tree oil so I have been but I just wanna know there’s light at the end of the tunnel! Lol
