I am just finding this mayo connect area to find out if others have incredible muscle pains post covid. I see you mention post arthritis like feeling post covid. I was competitive tennis player 2 weeks prior to me getting covid, and now 2.5 months later I can barely do any sort of slight exercise without huge muscle pain everywhere. I am hoping I can find some people on the forum to tell me maybe what type of blood tests to get post covid to find out why such bad muscle pain. My doctor's pass it off as if this is something normal, but it is not, especially for super active, in shape person pre-covid. If you know of any posts about what blood work to get to check muscle issues I am all ears, as my doctor's basically are doing nothing even after I tell them how painful this is. I keep telling them maybe it is Necrosis, or mytosis, etc. or whatever stuff happens after covid to muscle tissue and inflammation. Stay safe and well.
