Drentel - There was a time when doctors told patients with peripheral neuropathy to avoid exercise, but this has changed. Unless a specific case warrants otherwise, doctors usually recommend patients exercise as a way of treating the nerve damage.
Of course if running becomes too painful, a person with peripheral neuropathy symptoms may find it necessary to try some of the other exercises mentioned in the article. From my experience talking with patients, I recommend swimming. If you don't swim, biking is a good alternative. Both of these activities cause less impact on the body than does running.
