I am a 14 year old girl, and I have trouble breathing. I don't feel any chest pain or anything, but it always seems like I can't get enough air. This actually started when I was 8, then it went away from a couple of years. When I was 12, I started having trouble breathing after, and sometimes during exercise. I had pneumonia when I was 6 and was misdiagnosed as having asthma. I used an inhaler for quite a long time. Is this somehow connected to my breathing problems? I don't think its stress, because I'm not stressed at all. Or at least, I don't feel stressed. I haven't gone to see a doctor yet. Should I see a doctor about this?
