I have a huge bump in my armpit that hurts like hell. It's been there for several weeks now, and has not gotten a head on it, but I've still tried to pop it anyways (just in case). It won't pop, and it really really hurts. I can barely press on it, so a needle in it isn't working. Should I just stab myself really hard and endure the pain, or should I get a doctor to look at it? Stabbing the needle slow causes me too much pain, so I'd need to do it fast-like ripping off a band aid.
