A few days ago when I finally was able to see a neurologist for the headaches that started four months ago, the first part of his examination was of my feet. I had heard of referred pain, but this seemed extreme to me, and I told him so.
The doctor replied that he would get to my head. In the meanwhile he gave me a complete examination. He used a tuning fork, similar to what musicians use. I could feel it as he went down my legs. But when he got to each of my feet, I felt nothing.
Then he worked down my legs to my feet with the side of a pin. Again, my feet I had no sensation.
He told me that I had peripheral neuropathy. And I could see it for myself. None of my other doctors had ever told me that before.
