Nerve damage from Guillian Barre

I have recovered from Guillian Barre 9 years ago, but was left with nerve damage to both my feet. Both feet are still numb, and my right foot has dropped so I need to wear an AFO in able to walk. My muscle loss in my calf had diminished due to the nerve not supplying the muscle. I saw a nerve regeneration tincture from Dr. Schulze , and was wondering if anyone has experienced something like what I have or have used this nerve regeneration formula and had success with it?

Any suggestions are welcomed.

Thank you,
