Help I can't seem to find an answer? I have asked this in a couple of different forms and can't seem to get a good answer. Please help if you can. I have had a so-called cold off and on since christmas time. It gets worse each time and this time the cough is really deep, I have bad pain in my lungs (both) from my chest to my back. I'm wheezing constantly, I have coughing spells so bad sometimes that I can hardly breathe. I went to the doctor the first couple of times this bothered me and he just wrote it off to be my asthma being poorly controlled. I have had asthma for years and know this is not the problem. My boyfriend has told me that when I sleep I sound like I have liquid in my lungs. I think maybe it's pneumonia but i'm not sure. My doctor won't run tests. He's with the county clinic and all that I can afford. Should I go to the ER or is there some way I can possibly treat this at home. PLEASE HELP. I don't know how much more I can handle this.
