Hello! I am afraid I am still in pretty bad shape. I think I might have some Muscle Disease brought on by Covid they just can't figure out. I have many symptoms that mimic Myasthenia Gravis, but I guess Generalized because I don't have a droopy eye. I also have alot of symptoms that match up with Polymyositis. I just don't know what this is. The Rhuematologists say it is not Autoimmune even with a few positive ANA's and a high speckled pattern. All of my MRIs are clear. I had one EMG that was slightly abnormal for one leg, but the Neurologists did not make a big deal about it. I also had Genetic Testing that showed a few types of Muscular dystrophy including Limb Girdle Muscular Dystrophy, but the Specialists don't think it is MD either. I have alot of your symptoms. A constant dry cough, Low DEHA, cement legs, big heavy upper arms. My torso is very weak so it literally feels like I am walking a dead body. I did see an infectious disease Doctor that tested me for a bunch of diseases, but everything came back clear. He told me he would just diagnose me with Chronic Fatigue, but I have way more than that going on. I think it was that I was so burned out from working in Healthcare during the pandemic, going through perimenopause with caused anemia from severe periods and than getting covid on top of it. My immune system was probably already bad with everything going on and than probably fought so hard to fight up Covid with whatever I had left. It is almost like my DNA changed. Nothing in my body is the same anymore. Everything was attacked.I am so sorry that you are going through this as well. No one deserves this. I am praying that you feel better soon!
