Trying not to freak

Charles has been coughing now for over a month. It is a horrible cough. He has passed out 3 times from not getting enough air during an attack. He has been to the doctors at least 6 times. Because of his history of cancer the doc did a chest xray early and blood work. Everything came back clean. But that was over a month ago. The doc has prescribed at least 8 different meds and nothing has worked. So last week the doc sent him in for a cat scan and he goes in today for the results. Actually he is there right now in the room (he just texted me). I am so nervous. I am sick to my stomach and tears are looming. I have such a bad feeling and I am so afraid of the news. I know I have to be strong. I have 3 kids and I can't show fear or they will be afraid. But I have no where to let this out so here I am. All I want is for him to call and say that it is something easily curable. I am really trying to focus on the positive. All his other tests came back good and clean. So if it is something maybe it is early and we can take care of it. I just want to scream for help and I feel so desparate. I really don't know what to do. I think I will just go play with Emmy and wait for the call. I am so scared I can hardly breath.

***UPDATE****

Well the ct report said there were some lymphnodes that were larger than normal in his chest. But it is most likely a reaction to the radiation he had when he first had cancer. So this doc is now sending him to a pulmanary specialist to be sure. As far as his cough, his lungs look clear so it is being caused by a very bad nasal drip that is some kind of allergy. So now the doc sent home new meds. I am so done with this. It is like we get answers and also get new questions. So now he needs to make a new appt with the pulmanary guy. I feel like I will never get a good nights sleep.
