I didn't say 'medically' trained in my post. In Saul's original post, he made it sound that because 12,000,000 people had been treated with ozone with only 4 casualties that there would be nothing to be concerned about if one were to do ozone therapy in their own home.
Simplification can be dangerous.
With injecting ozone, there are many factors which have to be considered. There are many others. In a perfect world, it would be nice to have doctors providing oxygen therapies at an inexpensive cost. I am the first to realize that we're not in a perfect world. We all have to take care of our own health and steer it in the direction which we want it to go.
