So, I started getting a sore throat about two days ago. Yesterday the soreness went away, but the chest congestion and difficulty breathing, stuffy/runny nose began last night. I barely got any sleep because I couldn't breathe. I don't have a temperature at all, no body aches. Just the chest and face stuff. I'm starting to freak out thinking that it's the flu, and that's why I can't breathe! UGH help me out here.
