Okay. I'm 14 and I live with 2 people who smoke (my mom and grandfather), both really heavy smokers, so I'm obviously effected by 2nd hand smoke. About 2 years ago, I've started getting breathing problems. Short breaths, gasping for air, yawning a LOT, and during 45 minutes of Tae Kwon Do class, I get the feeling that I'm going to pass out, every time I go to Tae Kwon Do. During school, I sometimes get a pain in my throat/under my chin (cant really explain that spot) and feels really weird, the feeling is hard to explain. Then I get a tickle in my throat and start non-stop coughing. I also sometimes have serious headaches that really hurt. I also sometimes get chest pains. I can't smell it because I'm too use to it, but sometimes my friends smell smoke when they're around me. Thank GOD I got perfume for Christmas! I practically bathe myelf in it before going to school every morning! If people still smell smoke, I get soooooo embarassed and if they can tell its me, I tell them about my smoking mom right away. Is this normal or serious?? I gotta know now!
