if it is, then dont let it drain into the back of your throat as much as you can, blow your nose as much as you can also, dont just suck it back in and swallow it, this can cause the mucus to go straight into your lungs, which happend to me, and
everytime you cough, try to spit also, and
drink alot of sprite. that helps break it up. and just put some vicks vaporub on your chest. that helps me all the time... goodluck lol. it *****.
