Thanks. It was no joke and without a doubt the worst I've ever felt in my life. Waves of pulsing tingling fire spreading over my body every few seconds, only to find out my immune system was attacking everything, covid or not, on top of feelings of the flu multiplied by a thousand.
My doctors told me that if I hadn't had a capacity for deep breaths from working out and a strong diaphragm, there was no hope for recovery. Basically I had to force myself into excruciating pain every fifteen minutes and take and hold the deepest breaths I could via a spirometer to get my lungs "fibers" to break through the crust the covid was coating my lungs with. When your lungs get entirely coated, that's when you stop converting oxygen to your bloodstream. You can take breaths, but it's just the motion of it.
