Welcome Kim @kimroth, I'm sorry to hear that you developed neuropathy symptoms after your second COVID shot and now it's worse from the booster shot. The Foundation for Peripheral Neuropathy has some information on complementary therapies and supplements you might find helpful here - https://www.foundationforpn.org/living-well/complementary-therapies/.

Have you reported your reactions to the vaccine to VAERS? - https://vaers.hhs.gov/
