Oh man, I am so sorry to hear that. You may have Covid, but I seriously doubt it was the cause. Though it may have contributed. Sounds to me as though you have had a stroke, but I’m no doctor. Sp, I am merely speculating. But one thing is for sure, the hospitals make more money if you have Covid.
If lying unconscious for five or six days before being found, it is quite the miracle the OP is still alive. Going without water for three days is often fatal. Such severe dehydration causes organ failure and brain damage.
