I had COVID Jan 2021..shortness of breath and two months of low energy. Then two vacs and COVID again may 2022. Really bad COVID this time.felt worse than I have ever felt in my life! Still have loss of breath when walking. I am going to physical therapy now and also on LDN and methylene blue. Feel as long as I don’t overdo…I am getting better. I found a Dr finally that understands,is keeping u with LC research and thinks outside the box! It may be in vascular system??
