I am not sure I understand what you mean by internal vibrations, but since the Covid infection in January 2023, I have had what I believe is extensive nerve false or mis-signaling causing from major, multiple jerks in various areas to quivering twitches. These symptoms have been everywhere below my shoulders. Moving the area or body part stops it. This occured in legs, arms, on my sides, quads alone, calves, feet, and sometimes my chest area. The cramps have been excessive also. My potassium and magnesium are good as are all other areas which may be a normal causation for such symptoms.

Covid..... these are less in frequency now, but still present daily.

These are neurological as I am sure you understand. I find nothing, but time lessens them. I had them with an earlier Covid infection, but they were nothing like the current symtoms in ftequency or strength.

I wish I had something to tell you to help. Eat healthy, walk if you can for exercise, hydrate well, and keep pushing forward. You are not alone with this situation.

I have been waiting a year to see a neurologist in a group which focusses on Covid impacts. I have two other neurology appointments, one waiting a year, the other no date set yet. I do not expect solutions, but hope for guidance.

No vaccination, no booster. Major medicinal and environmental allergies preclude me from use on the full FDA label (not package insert). I have found nearly no one (doctors or otherwise) read the full labels of any of the vaccines. Regardless, the rate of production of these caused me great pause looking at the method. I have a Ph.D. in Plant Pathology and Microbiology and my work was host plant resistance and pathogen genetic variation on host resistance. I was in a plant breeding program.

We use and used these virus vectors and such in that field. It has caused some significant problems (vector virus transmitting genome to off target populations, pathogen resistance development, and other less significant issues).

Do you have pain with these symptoms or just the whole quiver - jerk situation which can be unsightly and annoying?

I note, when I become very relaxed, as in just before dozing off or resting quietly, this had the highest frequency of time occurrence.

Is yours the same?
