I'm so sorry to hear of the severity of your post COVID symptoms. I'm 18 months in and struggling with all the symptoms you have listed (and more). Diagnostics all coming back within normal ranges. I never had complete paralysis but had multiple episodes of sudden onset weakness - to the point, for example, of barely being able to lift my arm to brush my teeth or open the refrigerator door or feeling like my body was about to crumble to the floor. These episodes were few for me and only lasted 1-2 minutes. Never an explanation, though. I am accepted into the recovery programs at my local Post COVID Recovery Clinic and Mayo Clinic-Rochester, MN. Just getting started, but hopeful. The answers to our condition are so very hard to find. Hoping and praying for your recovery, with or without medical intervention.
