I slipped and come crashing down on my sacrum/coccyx 5 months ago. no fracture but pain when I sit for any time is excruciating. Fine standing or lying. But sitting upright on a chair at church or concert, pain becomes excruciating, radiating out in all directions. So little improvement over 5 months. Only had an exray. Did I briuse my sacrum? Crushed some nerves? What could it be? what can be done ? What should I request be tested and how next?
