I'm an 18 year old male. As of right now, I have a large, throbbing, fist-sized lump on the area between my upper thigh and buttock. This is not the first one of these that I've had, but this is the most painful, and the largest. I can hardly walk due to the pain. I want to go to the doctor and get help, but just looking at it myself makes me physically sick to my stomach. I couldn't imagine making someone else go near it. The only reason I'm asking now is because the anonymity of the Internet makes me feel less anxious. I would really appreciate some answers as soon as possible because I'm worried about how this is affecting my entire leg.
