Thanks Jill for your post. I had Covid in July 22 and then received booster only 3 weeks later which made me question - Was it Covid or booster that has caused these vibrations for 4 months now. Driving me crazy as I just wish I knew. I guess Covid as other shots never seemed to bother me. It's good to read from some that these tend to subside or dissappear gradually over time. Doctor just looks at me like I'm from Mars when I mentioned it. A lot of primaries and specialists know nothing about this.
