PN is relatively rare but increasingly less lately. I think it's because it is more frequent with age, and our senior population is growing. The baby boomers have become senior boomers. There are some very helpful posts on PN here.

See "SN in feet" on 2/19/23 by @larry4343. He linked a long, but excellent informative article on PN written by Mayo PN physicians. They recommend when doctors should prescribe alpha lipoic acid and in what amount. It's a good guide with helpful graphics. It's also great to know an actual prescription is not really needed.

@johnbishop posted very helpful links and attachments in "Small or large fiber neuropathy-What percentage is idiopathic" on 3/5/23 and in "Ideopathic Small Fiber Neuropathy Research" on 3/15/23.

Best of luck.
