I've had comprehensive testing for the neuropathy both locally and at Mayo Clinic. The general diagnosis was "idiopathic neuropathy". I also have Parkinsons. I've had the full NCS and EMG multiple times that show the progression. I've also had a nerve biopsy (nerve removed from right calf). That showed demyelination and axon loss. I've has multiple MRI and images of the spine from hi to low and multiple images of the brain. The general report is spinal stenosis. I did rely on one Orthopedic Surgeon for many years (9+). Where surgery was "off the table - I was not a candidate for surgery" direct quote. TODAY - after the epidural lidocaine and demexatrose (spell) (injection three days ago) I am pain free in both feet but numb. I'm assume at this point that the problem was the stenosis. I should add that the NP called the stenosis moderate not severe. Also, my back has been treated with "facet" injections every year for 5 years and this past year they performed an ablation (10 points). My back is actually pain free < 3 on my scale. Without facet injections the pain in the back is >7 all the time and crippling on occasion.
