Two in a half months ago I had adenoidectomy and sinus surgery. Still having weird pressure around my face and throat. Also it gets worst when I'm in the car, and someone turn the heat on (I had to put down the window to breathe a little better). And finding myself myself swallowing my spit a lot, and roof of mouth hurts when I yawn. If anybody can tell me some facts, I would really appreciate it. Because this been going on for a while. 24yr old male and been going through chronic sinus infection and swollen adenoids for a while now.
