I'm a 23 year old male, 5'8, and weight 183 pounds. I have excruciating pain in my rectum area. I went to the emergency room, the doctor did a rectal exam but couldn't feel anything. They did a CT scan and found a strand of infection inside my rectum. They said they think I may have a pilonidal cyst, but I don't see any pimples or holes near the top of my crack. I can't sit, and I can barely walk or lay down. I have not had a bowel movement in a few days, and now I'm having problems urinating. What do you think this could be?
