First off, I’m so sorry you’re suffering so badly. I too have Long Covid, going on 3 years in December without taste or smell. That’s the lingering one for me. I have body tremors now only occasionally if I stay up too late or am on my feet for too long during the day. I’ve stopped doing that! I also get severe cramps in my legs, not daily, but on occasion as well. I’ve started taking 2 Tums every night before bed and since I’ve been doing that (3 weeks) my cramps have subsided. Body tremors are much less than after my initial covid infection which was December of 2022. I’ve had 7 Stellate Ganglion Block injections through our big hospital Northwestern in the city of Chicago. They helped a lot with PTSD/Anxiety. They might help with your body tremors. I wish you good health!
