Tailbone pain â pain that occurs in or around the bony structure at the bottom of the spine (coccyx) â can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.
Aside from an injury, coccydynia can appear to be spontaneous. Tailbone pain and lower back pain can mimic coccydynia in sciatica, infection, pilonidal cysts, and fractured bone. Your doctor will rule out these causes to make a coccydynia diagnosis. The symptoms and examination findings of localized pain is typically all the doctor needs to diagnose coccydynia.
