Hi! I am an 18 year old woman and I was misdiagnosed with asthma (because of a mere cold) when I was a child as asthma is sometimes misdiagnosed. I was prescribed inhalers that I did not need. At the time, I didn't know what the symptoms of asthma were. Now, after doing a bit a research, I realize that I'd never had any chest tightness, difficulty breathing, or any symptoms related to asthma. My doctor won't listen to me so I'm planning to go to a different doctor. How can I prove that I was misdiagnosed? Height: 5'5, weight: 122 lb. Thanks in advance!
