I am experiencing this right now after a little slip on icy stairs. It's not so fun. There is a lot of movement that is connected to your ass, it turns out. The doctor told me this is a painful and long healing thing to go through. It's only a crack, but still...youch!
Anyone else gone through it? If so, how long before you could sit normally again or before your butt felt halfway back to normal? They told me 4-6 weeks for the bone to heal, but that is generally haunts people for a long time. I hope that's not true.
