From what I've read, an injury can cause PN, even years later. My pain from the ski fall was under good control from 2017 until 2021 when it suddenly all came roaring back. Not the tingling, numbness and pain that I have today. It was just pain in the lower back and buttocks. Then, back in December the tingling pain began to creep into my lower extremities. I never had foot pain before now. Going for MRI of feet to see if there is something awry there. Very frustrating.
