Possibly LE Nerve Entrapment

[milo]

if you have cleared all local structures, i would be looking and the lumbar spine. especially L4 - S1. there doesn't have to be pain in the back for it to refer pain. what i normally find is that, with treatment of the lower back, there is increased back pain as the distal pain and numbness subsides.

hope you ruled out saphenous nerve neurodynamically
