Hello and welcome to the NeuroTalk Support Groups.

I'll leave a couple of links to forums here where you may like to read and post.

Spinal Disorders & Back Pain Forum

Peripheral Neuropathy Forum

I ran a search in the Forum Search Feature for a member with Sarah in their name and posts relating to 'feet' and did find some by a member with 'Sarah' in their username, with similar problems as you, and they had posted on the PN forum (link above). If it's the same Sarah as the posts I found, they've not been here since 2011 unfortunately, but I'm sure other members here will have some ideas for you. Personally, I wouldn't rule it out being a spinal problem though, especially with your history, so please do check that forum as well.

I hope you find some answers to your situation very soon.
take care.
