Im so sorry to hear she is still so sick. I also have another friend that has had these tremors and vibrations, and jerks for over a year without much progress. I feel they are all related to hyperstimulation of the fight of flight. Basically Covid did something to our brains that is making us maxed out on stress hormones and anxiety which in turn causes all the tremors and jerks etc.

I have just started taking Zoloft to try to lower my overall anxiety in hopes it will help with my physical symptoms and sleep. I have never had an ounce of anxiety my whole life so to have all this now is crushing. I so hope this will change with time and better treatments will emerge. I will post on here anything that works for me.
