--basically to tolerance, as moving oxygen and nutrients into the damaged areas and moving toxins out is a definite prerequisite to whatever healing you may be able to get (and nerves do heal if the damage process can be removed, although they heal more slowly than just about any other bodily tissue).

I'm not surprised you didn't get much information from the oncologist; in my experience most of them feel out of depth talking about neuropathy from chemotherapeutic agents, even though many of those are notoriously neurotoxic.
