I have got such a bad pain in my coccyx, it feels like I have fallen over and whacked it, I haven't done anything to it at all! Every time I sit down I get such a bad pain, I can't sit on my bum I have to kinda lean a bit. The only thing I can think of that would be causing the back pain is that baby is back-to-back, but would that really cause this much pain?!x
