i've recently acquired a "keloid" or nose piercing bump. it's not too big, probably medium sized. but i've noticed that it's starting to look like a pimple, so i think it's filled with pus...it doesn't hurt & it's not very red, so i was just wondering if it's infected? i've been putting tea tree oil on it day & night :) i think i got it from getting a facial the other day & my esthetician's hand accidentally pushed against it :/ i've gotten one before but it never got any pus so i'm just worried...what do y'all think?
