I have had 3 Covid shots but now I am positive as of Monday Dec 9th 2022 .... I woke to feeling like I swallowed my electric toothbrush Dec 9th 22. I was vibrating and feeling very weird..I took my B/P at First my B/p monitor was hesitant but finally did a reading which was normal but the vibrating was very much still there....I sat calming myself or about 1 hour and final had to take 1 ml Ativan which help to calm the vibrations to a very dull tingle....I think I might be low on potassium or magnesium. I still have a odd feeling in my chest ,,Hopefully tomorrow will be better...
