What are the best available treatments for coccyx pain (tail bone pain)?

Depends: Can't say which one is the best. It is different in patients. Nonsurgical: physical therapy, manipulation, myofascial release techniques, medication, using donut-shaped pillow to sit, if not responding, then nerve block and injections or surgery to remove the coccyx if needed. Check with your doctor.

Consider: Consider being seen by an osteopathic physician. Osteopathic physicians have additional training in the musculoskeletal system and may be able to find the root of the problem or offer additional treatment or therapy (to include osteopathic manipulative medicine)depending on what is found on physical exam and further review of the history.

Coccydynia.: This sounds like coccydynia, which is a pain in the tail bone which occurs after sitting on a hard surface for a long time or from falling onto your tail bone onto a hard surface. Can take a long time to heal up. You can try sitting on a "donut", that soft cushion with a hole in the middle that you find at the surgical supply stores. Anti inflammatories and heat may help.
