Hi, I recently got sick and have been so for the past week. It started out with a bad sore throat that went away after two days when I finally began gurgling with salt water. Since I stopped taking so many cough drops, my cough got worse and sometimes I end up coughing up yellow mucus. I have a little discomfort when I swallow, but it's hardly noticable and since I don't usally look in the back of my throat with a flashlight, I don't know how long they've been there. My throat is also a bit swollen too. I was wondering if the white spots are because of my cold/flu or if they are because of something else.
