Glad your husband feel better with special shoes and Gababentin....
Unfortunately, the relief will not last long,,,unless properly treated neuropathy becomes worse and worse till prevent people even from walking...
First thing first you have to determine what is causing this neuropathy...a neurologist and a podiatrist is a must to see...they will check nerves conduction, arteries and venous blood flow, skin biopsy for small fiber neuropathy ( SFN) etc...
I got SFN three years ago, being on Gababentin and bunch of helpful vitamins to no avail....I've got to the point when walking became difficult. Finally I ended up with this clinic doing Sanexas treatment together with B12 shots straight in my feet along with some other life style changes..Sure enough, after three month treatment twice a week I got 70% healed, off Gababentin and walking with ease....I'm continuing to do Sanexas just for maintenance twice a month...Hope this help.
