nipple piercings??

Mine won't heal. It's been 8 months and not even close to healing. So I've decided I'm going to just remove them. My question is, have any of you removed them and how did they heal afterward? Was there a scar? Noticeable difference in your nipples? Im scared that these stupid piercings ruined my nipples... btw mine were inverted so I'm assuming they will go back to being inverted. Idk if that makes any difference
