Thanks for letting me know I am not only one got some crazy muscle stuff now, especially for someone that is competitive tennis player and runner right prior to covid 3 months ago. I am not even sure how you join into the Covid mayo clinic program, etc. as you mentioned, but I hope they also allow people that were not tested positive, etc. to join. Once I had the 104 fever and could barely walk, I was in the ER hospital pretty quick and they tested quickly for Covid. After that all the issues started happening with muscles than covid pneumonia. Hope we can all find the solutions to fix the post covid inflammatory response in the body. That is the main issue is the system is now tricked into thinking something is wrong all the time. It is similar to having Mast Cell Activation Syndrome, which I have been studying. I got on an H1 and H2 blocker to try per DrBeen.com youtube channel says might help. I will keep my eyes open for you to see anything that helps me I will pass it along.
