Can walking do anything to help with nerve regeneration?

Not specifically, however, exercise, as tolerated may improve the healing process by improving your general health. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV and Covid vaccines. Wish you good health!

Regular walking is an excellent exercise for your health stabilization, and should be a regular component in your lifestyle, but plays no mechanism in healing prior injured nerves. If the nerve coverings, "insulation" is damaged, recovery may occur over 4-6 weeks, but if the central "wire" (axon) is involved, the regrowth occurs at 0.1 mm per day.
