I'm 14 now and since I was like 5 years old I've had this barking cough. It's really annoying. The Doc's couldn't find anything wrong with me. When I was about 6 they put me on an inhaler thinking it was asthma. It wasn't asthma though. So I was back off the inhaler. I went to a Doctor before the summer because it was getting bad again. I had a chest x-ray and they couldn't detect asthma. It's really weird and quite annoying. Does anyone know what it could be?
