I did when I was younger, I have asthma (which has since gotten much better). My asthma was pretty bad when I was younger and I had several asthma attacks throughout my childhood. I had to go to the hospital in an ambulance a few times because of that
I've been fortunate to not have to be in an ambulance. Anything that did occur, either I drove myself, one of my parents, or later on my husband. I would not take the ambulance if I can help it. They are so expensive!
I dont think I ever have either. Ive always just been driven to the hospital when something was really wrong with me. Most people around here (especially those without insurance) will convince you not to call 911 and just take them to the hospital.
