I have had this cough for about 3 weeks now, and it won't go away, even though I've been on two different antibiotics and 3 different cough medicines and a pump. I went for x-rays and it showed no disease, lung infections or any phlegm in the bronchi. My phlegm is white, now I have a runny nose, and lots of white phlegm. Sometimes I cough so hard I can't breathe and my face goes red. Twice I started crying. It's not pertussis *whooping cough* or bronchitus. It feels like when I cough you can hear the phlegm, though it's coming from my upper chest/lower throat. I'm really worried, I get so dizzy after a coughing fit. Please help, I'm only 16 and I need to know what's going on, the doctor doesn't seem to know, except, "It's a virus".
I would greatly appreciate any help.
