Before you ask, yes, I looked up the symptoms on WebMD and got a ton of diseases that I'm fairly certain I don't have. The symptoms I have are: a terrible cough (it's gotten worse in the past day, but I've had it for longer), a headache (which only just recently started as well), and a sore throat. Anyone have any idea what I have? I have to go to school in about an hour and a half (timeline), and it's especially important that I go because I have to take a geometry test. The only thing I could think of is that I have a cold, but I just want to make sure.
