It started as what seemed as really bad allergies. My nose was stopped up really bad and I was sneezing quite a bit. I developed a mild sore throat but it went away on its own. That was last weekend. All this week my nose has been stopped up. In the past few days it has been better but this cough wouldn't go away. The cough wasn't really bad its just that when I cough I would cough up phlegm. And eventually the cough slowly went away. It still comes back but no where near as bad. But the phlegm or mucus just won't go away. Instead of coughing I find myself clearing my throat or lungs to get the phlegm out. And when I do it makes me dizzy. The school nurse gave me some cough medicine but that just makes me sleepy also.
