question: Hello i am a 22 year old female i have a really bad cough that wont seem to go away, i have been coughing up mucus that seems to be white at times then watery and clear the next at times i will cough to the point i throw up, i have lost sleep due to cough spells as well i had this issue about two years ago and had xrays done on my lungs and the doctors said everything seemed to be clear, but lately i find it hard to breathe if i try to get a good draw of air i end up coughing or wheezing.
