@ray666 -- Rsy, sounds like you have the information together for the doctor. When I went to Mayo in Rochester, the timeline of my progression, along with testing, helped the doctor give me a diagnosis, not a cause but where the nerves are being damaged. Lately, I've been scratching my head wondering why peripheral neuropathy impacts most people in their 60's and 70's. Again, I say most because I'm aware this horrible disease can affect folks well under 60 years of age. My wife recently reminder me that I talked about a tingle in some toes back in 2007 when I was 57. She remembers, I don't. So, I guess that is when the numbness likely started. A mystery for sure.
