I'm reading a previous post of a patient complaining of a hard lump on the butt cheek after a fall on wood stairs. This same thing happened to me several years ago. I fell, hard, and hit the edge of a stair right on my butt cheek. It was a searing pain and I actually thought I broke my hip at first. After 30 minutes, I was able to get up but I had severe pain, a black bruise on my entire butt cheek for about a month, couldn't sit on that side for several weeks, and a huge lump formed across my whole cheek. It's larger than my hand. It's been several years and has not dissipated. It is as large as it was in the beginning and is still bothersome. I have a lot of pain in my sciatic area, hip, and the lump itself gets tender after prolonged sitting or pressure to the area. My Dr. Said at the time that it was one of 2 things, one would go away, one would be there forever. Can't remember what they were and i'm assuming I have the lifelong injury but my question is. What is this injury called and is there anything that can be done do reduce the lump or level of discomfort and pain?
