I’ve been wondering the same thing . After my 2nd vaccine neuropathy jumped all over my feet , and now up my calves . The tingling and tightness at my ankles is unbearable. The neurologist said I have neuropathy, I shouldn’t be able to feel my toes , but I do , he said I shouldn’t feel the cold or hot at floors , and bath water , but I do . I asked him some straight up questions, and he said I don’t know , he said he doesn’t specialize in neuropathy. So , I feel hot and cold at my feet, I also feel pressure… like driving a car at the petals. It’s all strange to me . I’m tired of all the adds to fix neuropathy, snake oils and such . I truly hope someone can help
