Recently my entire high school has been getting sick. Everyone is getting sick everyday day. I've gotten sick and the symptoms I've had are: Deep cough, Sneezing, and headaches. Now most of those symptoms have stop now I'm just spitting up mucus. I am a singer, and currently I can speak perfect without problem. However when I try singing its just a bunch of air that comes out and I can not seem to figure out why. I feel perfectly fine except the coughing and mucus coming.
