Coccyx area pain

Hello kind people, 35 M here. Has anybody here recovered from tailbone pain or coccydonia? Looking for tips and personal anecdotes!

It’s been a year since I fell on my tailbone, fortunately there was no fracture, or dislocation, however, I ended up with two disc bulges at L4 and L5, and tailbone trauma.

The tailbone doesn’t hurt anymore, however I can’t sit for too long before the muscles tighten up and start hurting. I used to be a long distance runner, I can’t run anymore, that hurts the tail bone area in a deep visceral way.

I have been to PT, I do stretches(McGill) and pelvic floor exercises, and I have also started going to the gym, which fortunately has been pain free after a lot of adjustment.

For people who recovered from a similar problem:

1. What treatment or exercise made the biggest difference?
2. Did piriformis or hip-flexor stretching improve your sitting tolerance?
3. Did pelvic-floor physical therapy help, and did it involve internal assessment or treatment?
4. Did anyone benefit from shockwave therapy, injections or a coccyx specialist?

Thanks
