Doctor's and Chest X-ray's

So what a fun afternoon I had....SLASH NOT! I spent an hour in the doctors office- shocking it wasn't longer lol..... and then he sent me for a chest x-ray... I've been sick since Feb so thats 4 months now... I was better for about 2 weeks and its coming back again (no worries its not swine) and to the happiness of my family its bacterial which means no one i'm around will get sick - its just a bad bad cough and kills my energy - when it first started i couldnt drive more than an hour without having to pull over for a nap... it was bad! I've been told it sounds like croup but alast it is not... we're not sure what it is so i'm kinda hoping that this x-ray brings something up so at least i have a reason for this cold :(
