Mayo Clinic diagnosed it as "Long-standing length-dependent sensory & motor painless peripheral neuropathy." They could not determine why I have it, therefore it is idiopathic. They said they suspect it is hereditary (although I doubt that). I have progressively worsening balance, plus drop foot, although I can still feel things on my legs and feet. I wear foot-leg braces on both legs and use a cane. It is getting so bad that my physical therapist is recommending a walker. I would LOVE to know why I have this. I did drink more alcohol than is recommended for a woman, daily for about 18 years, so I wonder if it can be alcohol related. However, it came on slowly and I have no tingling or pain. I welcome hearing about anyone else's experience like mine.
