Hey, I'm kinda new to this site so I'm not sure if I'm doing this right but anyways I'm 18 and I've been smoking for about 6 months (really bad habit and I'm wanting to quit but can't seem to stick to it) anyways I ended up getting a cold.. Stuffy nose and a cough... Well the cough has gone and so has the stuffy nose however when I go to laugh hard at a joke I'll start to cough or sometimes if I talk too much I'll have a bit of a wheeze in my voice which will make me cough... And when I cough it's really mucusy ... Should I be worried or what's happening? Please help
