I have a bent coccyx bone. It happened when somebody kicked me, then a week later I slipped on the back verandah and banged it on the table.
I had some x-rays done and it turned out that I had bent it right. I have just seen a specialist after 6 months of pain and he said that it should heal in another 6 months.
If it isn't better by then, I'll have to look at getting an operation.
Thanks for this site it has really helped me in knowing that other people face the same problems as me.
