Hi @bmelvin,
Very sorry to hear about your condition. your doctors are probably already aware, but I saw a paper by researchers at Mass General. They found that in some cases, post-Covid vaccine neuropathy was due to an autoimmune response. They were able to successfully treat most of the patients in their cohort with steroids, and/or IVIg. I’ve posted a link here in the past but you can probably find it faster by google, or by going to the publication section at the neuropathology Commons site. Best of luck.
