You are not alone. I have had Long Covid for 18 months. My feet have pins and needles, my skin 'crawls', I get jabbing pain between my toes, and what can be described as 'pop rocks' up and down my legs. I've also been noticing that my body feels like it is humming in a vibrating kind of way, if that makes sense. Also lightheaded with a headache that just won't quit! I am short of breath on exertion and have developed dysfunctional breathing. I can't seem to regulate my temperature anymore and frequently have a fever. I'm losing count but I had 3, maybe 4 Covid shots and one Covid infection. I've learned that I have a compromised immune system (unknown to me prior to Covid) as I have tested positive for Epstein Barr, Lyme, and am Hypothyroid.
