I had chronic lower back pain and sciatic numbness for years and completely separately (or so I thought) problems with my knee (going down stairs was excruciating). The knee pain was dx'd as IT band / piriformis syndrome. P/T for the knee coincidentally helped alleviate the lower back pain and sciatica. I eventually got into Pilates which seemed to help stave off all three problems (until Covid). I have a degree in English lit and zero medical qualifications but it sounds like you compressed the sciatic nerve on the ride. Can you get your doctor to recommend some P/T to try to release that?
