I find your story fascinating as while mine not exactly the same had similar component of a herpes family virus precursor.. I had Shingles in July started with lesions In left groin region and then it butt crack leading to bilateral neuropathy in my calves. Resolved after treatment then four weeks later started develop neuropathy in the right hand that progressed to a full body neuropathy followed by thethe fasciculations everywhere. I had two negative EMGs and NCS by neuromuscular specialist’s. Nothing showed up extensive lab work. I’m convinced it’s the immune response to the virus.
