The APTA (American Physical Therapy Assoc) has a section of Physical Therapists that specialize in Pelvic Floor Muscle Rehab. If you can find someone in your area that has extra training you may find the relief your seeking.
Depending on the injury you may have a hypomobile or hypermobile coccyx. The muscles that attach to the coccyx may be in spasm or pulling your coccyx in one direction more than the other.
The nerve that is usually involved in the pudendal nerve.
Quick tip: try putting pressure between your "sit bone" and your rectum. Hold the pressure for 30 seconds and see if you get any slight relief. If yes you can try using a racquet ball instead, hold the pressure, don't bounce, if pain doesn't relieve in 20-30 seconds this may not be for you.
I am in the womens section of APTA and would encourage you to call 1-800-999-APTA to find someone near you who can properly evaluate your muscles!
Everyone is different and physical therapy may not be your answer but it is a good place to rule out muscle/nerve involvement.
I was interested to read the message from Christine Fitzgerald regarding pelvic floor exercises. I have had coccydynia for 22 months and have tried many things. Three months ago I saw a physiotherapist with specialist knowledge of the pelvic floor. She suggested pelvic floor exercises. I believe my condition has improved about 25% so far. (These exercises are very tedious and I rarely do them as regularly as suggested !)
