I have a hard lump on my right butt cherk. It's seems like swelling but it's hard to push. It doesn't really hurt but there is a small amount of pain when I push on it. It scabs over after rubbing. When scabs are removed clear liquid oozes out a little. Also the is swelling on my right hip and also on the right side of my upper pelvic area. I have no idea what's going on. I'm on hiv meds and recently started taking them again. Idk if that may be apart of the problem.
