I fell down the stairs and whacked my right bum cheek on the step. The pain was horrendous. I can’t sit down! But worse than that it’s left a big step shaped imprint/dent on my bum. There’s nothing there to break is there? I’m quite fat and I can move so don’t think it’s my pelvis. It’s just like the fat with a dent in it. It’s not getting any better a few hours later.
