question: I appear to have coxcydinea. It started 2 weeks after L3-L4 decompression surgery. I think I was spending too much time leaning back on various chairs. My MRI shows slight angulation, but not much according to my neurologist. I may go see a physiatrist for a ganglion impar bock. I also just started with a PT who does internal massage of  the muscles and ligaments connected there. am I on the right track?
