Hi everyone- I'm new to this board. I have been suffering intense right leg pain for 2 weeks, it started in my upper outer thigh and made it impossible for me to walk unless I crouched down and put a lot of pressure on my right thigh. In the next day it progressed down my right lower leg, on the outside, very painful, constant. Icing helped numb it. Then my lower leg went numb (on the front) but still intense pain in both upper and lower legs. MRI showed widespread degeneration and stenosis in all lumbar vertebrae which my GP was was ago normal, and yet I have no pain in my lower back (I am 76, have been active all my life, have done 3 ironman in my 60s, and more recently have been doing reformer pilates- and swimming and bicycling) . A new chiropractor thought it was compression of the lateral femoral cutaneous nerve, she did some nerve flossing with a blunt steel on my right outer thigh and some point-pressure movement of my leg, plus SI adjustment with drop table (my right SI has been a chronic issue). After, I was able to slowly stand up straight and walk slowly with less pain- but within a couple of hours the pain was back.
Has anyone had similar leg pain with no lower back pain? Can tight muscles cause this nerve compression? It came on out of the blue around noon on July 7, with no triggering activity (I had been swimming earlier that morning).
I had been on a 13 hr plane flight back from Europe on June 10 (thus a month earlier), but had no issues.

I'm trying to see a spine doctor and hope for a steroid injection in the L2-4 area even though I don't have pain there- can femoral nerve pain originate from a compression leaving the spinal column but only manifest pain once it reaches the thigh?

Thanks for reading this- look forward to any insights/ similar experiences.
