Pain in the toes can certainly be from neuropathy and can be an after-effect of GBS. A lot depends on the nature of the pain, when it occurs, what (if anything) makes it better or worse and other factors. It could be managed by your GP with medications such as nortriptyline, gabapentin or pregabalin or you could try to get seen by a neurologist in Auckland. Unless you go in private you can’t really choose a specific neurologist. Gareth
