I've been having pain in the area around my tailbone for about 4 months now and it's been getting progressively worse. I went to the doctor and she did an external exam and didn't feel any masses or cysts, so she sent me for an xray which came back negative for any fractures. The pain has been spreading upwards into my lower back and also into my right buttock, and it hurts to sit at certain angles and is excrutiating when I first stand up after sitting for long periods of time. Also, I fell down a set of stairs in November of last year and hurt my back and tailbone, but the pain subsided. I've benn having recurring back pain ever since, but my tailbone only started hurting a few months ago. Any suggestions?
