@heisenberg34 Also I just realized you were a cyclist and believe me the seat can do lots of damage to buttocks and lower back tail bone. That's why I think you need hands on therapy. I would also suggest to see an orthopedic surgeon. You might have a slight fracture of the tailbone and that can cause horrible pain. Just look into everything possible if you doctors haven't and if they give you the answer there is nothing wrong, be your own advocate and find another doctor until one listens to you and checks out what you are telling them. Good luck.
