@tw508 I know in sending me to a neurologist to try to disprove ethambutol caused this he sent me for an MRI results still pending and told me to take riboflavin he said B1 supps but that is not riboflavin but thiamine. B2 is riboflavin together with magnesium. He said it would help with migraines but not sure if he was thinking it might help the neuropathy as well. No mention of any other B vitamins.
