Industrial bar bumps?

I've had my industrial bar piercing for about.....7 or 8 months now....I have little lumps on both holes on both sides :/ and they hurt...I know the piercing isn't healed till the full year but do you know how to get rid of these awful bumps...I've herd they are hypotrophic scarring NO KELOIDS...I know what those are and its not that...I've been using tea tree oil once a day for a while now but its not helping :/ help?! <3
