Most people that think they have a coccyx fracture
will relate to direct trauma to the area.
If you touch the area after an injury and it remains painful then it may or may not be fractured. A coccyx fracture is very hard to see on xray. Even if there is a fracture there is not much to do for it, but observe. If it still hurts 8 weeks down the road then you should see an orthopedist.
