One is not really in a position to refuse help/antibiotic treatment with this severe infection. So you are more or less stuck with the side effects of the drugs used.

I'd really recommend Kefir for your control of this infection.

Acetyl Carnitine and CoQ-10 and R-lipoic acid are typically used in drug induced nerve toxicities.
