Brief Answer:
An Xray would show if you have a fracture

Detailed Answer:
Hi,

Thanks for you question.

I'm sorry to hear about your fall. You could have fractured your sacrum or you coccyx. An X-ray would usually show this but not 100 percent of the time.

Low energy sacral and coccygeal fratures are usually managed non-operatively with analgesic such as antiinflammatory medication, tylenol and opiate, morphine derived,drugs in the early stages when they are particularly painful.

Sitting on a soft cushion/pillow or dognut ring can help relieve the pressue. If you fell unsteady on your feet then a cane or crutches can be of benefit.

I hope this answers you question.

best wishes
