Diagnosis was neuropathy with unknown cause..... Blood tests have determined not diabetic. No real change in blood test from a year ago except little low on Vit B12, which I checked and affects nerves. I am now taking this. Started a few weeks ago, extreme sensitivity in my right knee and legs, numbness in toes and feet........anything touching was a problem. Problems sleeping....I have a history of restless leg syndrome from time to time, so got up, walked, elevated legs, etc. it got worse......I am now experiencing it to some degree all the time. Will check website....Thank you.
