Anyone know what this could be? There are 2 round white bumps on both sides of the back of my throat. I also have a patch of white on the very back...like behind the uvula (spelling?) going down my throat.

My throat's been really sore, mostly on one side. I also feel dizzy when I stand. Not sure if that has anything to do with spending most of the day in bed or not. Anyone know what this could be? I don't have a doctor's appt until the 18th
