I had a heart attack 5 years ago, I am over weight, and I'm 50. Other than that, no pre-existing conditions. But those I'm sure those were enough to explain why I had it so bad. They were VERY worried about blood clots. I was put on Oxygen, and they treated me with Steroids of all things. About every other day they would put me on a machine looking for clots. I spent 17 day sin the hospital, 7 of those in the ICU. I had "long Covid", whatever exactly that is, for about 6 months. My wife and daughter both had very mild versions of Covid at the same time. All of us did take Ivermectin as soon as the first symptoms started showing up. I'm pretty confident that helped saved my life.
