My neuropathy was caused by a (first small, then large) disc herniation. The small “bubble” out, which I ignored, caused numbness between two toes on one foot for several years- then it “blew”, causing very advanced symptoms. The MRI also showed spinal stenosis, which is very well-known to cause leg weakness. I sought care at a major medical center/teaching hospital. You are on the right track. If they refuse you, call the next one. Good luck, my daily neuropathy prayer is “Help me to acknowledge, accept, and choose to work with my disability.” It’s hard, but like Jake says, “It is what it is”.
