I really don't know! My doctor took me off of a medication too for G.E.R.D., which I think it did not help my neuropathy. It was
Omeprazole 20mg in the A.M.
I think you have an excellent questions because so many meds can affect nerve damage, especially in your feet first! I sure hope some can answer this question. I am an amateur and feel I can't answer this question, Although, my Neurologist, suggested my neuropathy can be attributed to some of my numbness. Plaquenil for my Lupus.
Hope this helps someone! Good Luck! Pat K.
