A couple of days ago I noticed my gum at the back of one side was tender. My gland on that side was up. It's been getting worse since then - sore to open my mouth, tender along my jaw and down my neck.
Today one side of my face is visibly swollen. Feels like fluid (nice!) What could it be??
I've had no dental work, no cuts, nothing. My gum doesn't look red or inflamed/infected. Help!
