I have had this thing in my armpit for months. It is a huge eye sore and makes me feel gross and it hurts to shave! I used to think it was a pimple, but there’s no way it could be there that long. I don’t think its a mole either because it’s not something I’ve always had and it basically happened over night. I thought it could be an ingrown hair from shaving, but if that’s the case what on earth could I put on it or do? Please help me out ladies this is getting old I’ll post more pics if you cant really see it in this one just leave comment
