My initial symptom, which started 2 weeks after the first Pfizer vaccine, was muscle spasms in my feet. I subsequently developed sensory and motor peripheral neuropathy. I have some fasciculations. Many people in the Neuro V Long-Haulers group on Facebook are reporting fasciculations due to the vaccines. The doctors don't know how to treat us because this is a new phenomenon due to the new Covid vaccine technology. Many patients are reporting like you that their only abnormal test result is TSHDS.
