Over the last 2 weeks I've had a mildly swollen uvula. It causes me to gag often its very bothersome. I had a cold about 2 weeks a go but that has since subsided. This thing just persists. I mentioned it to my doctor at the time and he didn’t seem concerned. But now it’s on and off all day. I really want to Google it but I'm afraid of the anxiety it will set off. Any advice?
