Hey, I've been having this weird jaw pain right at the hinge, and I think it's a bit swollen, but only on the left side. I just had some dental work done on that side because of a cavity, and now it hurts to open my mouth wide. This all started last night, but for about five days before that, I'd wake up with a sore throat, a runny nose, and mucus. Strangely, during the day, I feel fine, but at night it all comes back until morning. There's also this occasional ringing noise in my left ear, like a beep, and it's around 814kHz or something. It's more obvious when I cover or muffle my ear. Any idea what's going on?
