Don't get dscouraged, everyone thinks their experience makes them an expert. It is called idiopathic NP because they have not gotten very far in finding a cause or universal treatment. My MDs have me on loads of vitamins and other suppliments and we have tried the recent meds used for the conditions, they work for some, but not all, everyone is different. Its a trial and error issue. But don't forget Physical therapy and things like boots laced up to you knees. I found that a pair of $200-300 boots custum fitted for me allowed me to forego a walker and greatly reduce my dependence upon sticks. Physical therapy has focused on transferring my balance more towards vestibular and visual. But I have severe visual problems also, but it all helps. If you are uncertain about your neurologist get a second opinion or third, this is not a simple problem and it can get really awful as I am sure you are aware. I am headed for more spinal/neuro surgery to releave the neuropathy generated by stenosis etc, it is a long battle. Remember Medicine is more art than science when it come to diagnosis. And by the way everyones experience is important. I love my boots, I can walk again!
