About a year ago my husband began to lose feeling in the bottom of his feet. He describes it as feeling like his feet are "fat". At the time he was doing in-line skating for exercise, and thought perhaps it was from vibration of the skates. However, winter came, and when it was wet, there was no skating, and the problem continued. He went to his doc. A blood test for B12 deficiency was negative; he was sent to a neurologist. The doc may have done other tests also; I was so certain it was a B12 issue, that's what I focused on. At the neurologist, no reason for the lack of feeling was found; he was told, come back in 6 months if it continues. It has gotten worse. After reading that blood tests for B12 are not as accurate as newer tests, he began taking 1000 mcg of b12 2x/day, thinking that it won't hurt, and if it is a B12 deficiency, it would take care of it. Has not helped. He has given up coffee, wondering if that could be related? His next appointment with the neurologist is mid-April. Meanwhile, we are very concerned! What could this be? What should we try? My husband is 63, eats a plant-based diet, has a TC of 155, and is active.
Did the doctor check his vitamin D level? Vitamin E? Thiamine? Maybe he has an absorption issue. http://neuromuscular.wustl.edu/nother/vitamin.htm
