This is how my long covid symptoms started. I was not aware of LC as a thing. I'm 4 weeks into it now. My symptoms are like Chronic Fatigue Syndrome. I had good days and bad days. I only found out about CFS in the past week. Please research it. Learn what 'crashes' are and what causes them. I'm still doing the research myself. Some people never recover from CFS, there's a lot to learn and understand about it. Avoiding crashes is critical to not making the disease worse.
