There is one more disease modifying drug that is very common in autoimmune disease/neuropathies...Plaquenil. It's an anti-malarial used as a DMARD.

It may not actually 'fix' the neuropathy, but it does aid in control/slowing progression of autoimmune disease...therefore possibly indirectly helping the neuropathy.

Maybe I should have waited to comment when you address that particular group. Anyway, I'd be interested in hearing your comments on Plaquenil.
