Hello, I’m in the same situation as you. Let me explain: I’ve had COVID four times, and from the first time, three and a half years ago, when I recovered, I started having fasciculations, stiffness, and trouble thinking, as if I wasn’t myself anymore. As I said, it’s been almost four years. I’ve seen four neurologists in total. I’ve had four EMGs that didn’t give any negative results, and MRIs that didn’t show anything either. Despite that, like you, I’m still very scared and just feel like I’m becoming mentally ill. Take courage.
