OP, welcome

GBS is not rare from the vaccines which are all experimental. There are many issues that are being reported from those doing the shots.

I would be loading up on Vit C, Vit D, Zinc and other antioxidants to help to calm and reduce what you are going thru.

I've used Inosine and reported that here long before any covid issues. I don't have issues but Neuropathy has been around a long time. I've been taking Grape Seed Extract for many years and have talked about this supplement here for a long time.
