I am 16; 5'7", and approximately 198 pounds. Several months ago, I got a lump under my arm. I've seen 6 doctors for it, and each one has given me a different story. The first one thought it was an abcess. The second thought it was a cyst. The third thought it was an infected sweat gland. The fourth and fifth thought it was some other minor infection. The sixth has decided that it's MRSA. The third doctor performed a surgery on me about 3 weeks ago to remove the sweat gland, but I continued to get worse. What I have is a hole, in my armpit, that is very painful all around it, and is red, and is currently draining a greenish pus. None of the antibiotics I've been put on have done anything to help me. I don't know where to go from this point. Or how bad this infection even is.
