OK; lots of folks here who can help with that.

There are many causes/types (100+) of peripheral neuropathy; in some respects they're similar and in others quite different. The same goes for the symptoms and pain that they may/may not cause. PN is kind of a 'full-spectrum' condition; it can range from a minor nuisance for some to a full-blown disability for others. Given the diversity, I think it would help us help you (collectively) if you could tell us what you know about your partner's PN—cause (if known), test results, onset & progression, symptoms, supplements, treatments, any known 'triggers', etc.

Like anything else, the more we learn/know about something, the better we can cope/deal with it.
