I have muscle cramps and spasms that began following a tetanus booster (first in 14 years). This has been going on for almost two months.
Nerve conduction velocity conductivity, MRI & spinal tap look fine. I had a Lyme test with 0 bands on the IgG and all three bands on the IgM.
Is it possible that a tetanus triggered something that's been lying dormant in my body?
