persistent cough

I have a presistant cough. it's uncontrollable and sometimes hard to catch my breath as I'm coughing a lot. if I cough too much I feel like I'm going to throw up. occasionally white or yellow phlegm or mucus comes up but that's only pretty occasionally. when I'm not coughing I have shortness of breath, cold sweats, headaches, dizziness, gross feeling in stomach. I do plan to go to doctor on Tuesday or so since I've had this for 2 weeks and no sign of it letting up. but I'm wondering if this has happened to someone else with same or similar symptoms and what it ended up being?
