Hello, I have a few issue's around my pelvis. I have a odd shape, hard lump (non visible), under and inside my right buttock. It twitches ,itches, and I can feel it without physical touch. I have not been injured there and it started enlarging 4 months ago. I have also had a very sore cocyix with also Pilonidial Cysts that inflame,bleed, and drain that many strong antibiotics given through doctors have not been able to control. I have problems sitting and it takes a few moments to straighten out and walk without discomfort. It also is sore when I pass gas or go the bath room. What could it be and what should be recommended? I have a white patch inside my rectum (where a polyp was removed 4 years ago) and have very loose stool movements along with itchy rectum. Hope I can get a opinion about this. Thank you.
