question: Hello, I am having trouble taking a deep breath. sometimes i have to yawn to take a deep breath but even that doesnt work. my chest hurts a little bit. i try to take a deep breath but it seems like the air gets stuck at the bottom of my throat and doesnt get to my lungs. its very off and on sometimes its easy and other times not so easy. I am 21 years old. I have Wolff Parkinson White Syndrome. What I don t understand is that when I am active, playing basketball or any sports running my breathing is normal. chest doesnt hurt and i can take a deep breath with no problem. Do you have any idea what this could possibly be?
