Since you mention that you were diagnosed ten years ago with a hereditary neuropathy perhaps you should pursue having DNA blood testing to hopefully find out what you have. Sounds like your father also had it. If you do not mind sharing, what other symptoms do you and your father have?

DNA blood testing is expensive. Perhaps insurance would cover the cost. If it turned out to be something such as CMT there is no cure/treatment at this time. There are over 70 types identified so far.

If CMT were the case it can be exacerbated by going too far with exercise. No pain, no gain is not for a CMTer.
