Those were also my original symptoms upon vaccination late summer 2021. On one visit she did say they were not typical MS symptoms. The MS diagnosis happened after a spinal tap contained oligoclonal bands ie. Elevated proteins. What confuses it all are a few bulging discs. The spinal cord lesions are in close proximity to a bulging disc. I have wondered if a disc issue and poor posture moments can cause those vibrations. My most recent MRIs were only a week ago so I will have a follow up before November is done and I will ask more about the cyst. I do have trouble sleeping and do wonder if that's a melatonin deficiency.
