Thanks for the information. I used to be a runner, but have had ideopathic neuropathy in feet and legs for quite some time now. My temperature and pressure sensitivity is good, however my vibration and position sense is very poor. Also I really don't have any reflexes in my legs. Although the exact cause of my neuropathy not been identified, I suspect I have demyelination of my large nerve fibers causing the primary problem. At this point I am focused on physical therapy and looking at various alternatives. I appreciate your thoughts.
