Everytime I inhale I have to cough and when I cough its really crackly. I dont have a fever or any others signs of a cold or the flu. Either if its a short breath or a deep breath I have to cough badly and I cough stuff up and the stuff I cough up tastes like throw up and sometimes if I am leaning over coughing saliva comes out of my mouth like drool. When I cough it hurts my throat. What is it and what should I do about it?
