I'm really worried because I've been coughing for two weeks now, and it's getting to the point where sometimes when I cough really hard, it completely blocks my throat and I can't breathe. It's scary, and on top of that, I've actually thrown up what I've just eaten a few times. I already saw a general doctor, but the meds they gave me aren't doing anything. Can you tell me which specialist I should talk to about this?
