I'm so sorry that you are suffering this much! I developed sensory and motor peripheral neuropathy after the Covid vaccine. I suspected involvement of the dorsal root ganglia neurons because 3 neurologists agreed that my presentation was unusual. The nerve pain and numbness in my feet were dramatically increased by sitting. There are a lot of ACE2 receptors in the DRG neurons. There is evidence that my nerve damage was autoimmune-mediated. I am slowly recovering. You could find help and support at React19.org, which was founded to help those with injuries due to the Covid vaccine. When funds allow, they give grants to those struggling financially.
