Partial or complete regeneration of simple tissues (as opposed to whole complex organs), meaning healing, takes place in healthy people all the time. Even the damage caused by illness heals in healthy people after the illness passes. An example is bacterial damage to the throat membranes caused by strep throat. Our throat tissues heal and gradually stop hurting after the infection goes away. The problem with most of us here with PN is that we are not healthy, so our peripheral nerves do heal.

I think that inflammation is the root cause of the myriad ills people describe in this forum. Inflammation prevents healing or even causes progressive damage. Our general high level of inflammation can have many causes usually acting together. Examples include aging, exposure to drugs or other toxins, infection, allergy, lack of exercise, poor diet, poor stability of blood glucose, hormonal imbalance as with chronic anger, or chillingly, covert cancer.

For most of us, reduce generalized inflammation and our neuropathy and pain will either heal or get considerably better and stop progressing.
