I never had Covid, but had 2 vaccines and 3 boosters and shortly after have Neuropathy.. I am sure it is from the vaccines, and my husband wants to have the 5th booster but I am not going to. I am lucky so far, as it is in my feet, started with the toes and has spread along to my heel and going up my leg is a little numb. And I dont get too much pain. I have torn tendons in my arms and they are very painful and not sure if the Neuropathy is affecting them.. Also have bad Arthritis all over so not sure if also worse do to Neuropathy. I have an appointment this week for a Electromyography Test so hoping that gives me some answers... Hope you find something to help your pain....
