@munira12, neurologist diagnosed me with B12 deficiency. He thought I had been sufficiently low to cause my symptoms. I also had tingling, numbness, fasciculations, hair loss, loss of smell, internal tremors, etc. So….idk, was it all related to my post covid syndrome? Idk. My first neurologist said not neuropathy, as has several orthos, but……I’m not sure. Trying to stay healthy and follow up with spine scan sometime soon. Keeping an open mind.
