@rickhood - My symptoms are not exactly like yours but close. I do not drink alcohol, all blood work comes in normal like A1-C, not diabetic. B-12 was in low range and 1500 mg daily keeps numbers up to normal. I have lower back problems L-3 to S-1 but multiple MRI's indicate issues but not to the point of surgery. I too have numbness but no pain with poor balance. My neuropathy developed into bilateral drop foot. I also take many of the same supplements you do, not much help. A head scratcher to say the least and I've been to several top places including Mayo. Weight? I think you are right. I've been able to cut back on food and have lost 10 pounds since April resulting in less back pain but has not decreased numbness.
