Hi guys. My 5 yr old has been inhaling extra hard since thurs/fri last week. At first we thought he was doing it for the sake of it, but when he came out of school yesterday, he said he couldn't breathe so good at playtime, and his chest hurt. I rang the docs straight away and got him an appointment there and then. The doc gave him a thorough check over, and dismissed asthma (which I thought it could have been) he said it was probably a pulled muscle, but didn't give us anything and sent us on our way. He's still breathing like that, and I'm starting to doubt the doctor. What do you guys think?
