hi. I noticed i had pain at the back right of my jaw and didn't think much of it, today it got really painful and swollen to the point that i couldn't touch my back teeth together without having to skin in between, then as i whent to the bathroom i looked in the mirror and pulled my cheek out to once again check on it, as i did a LOT of puss squirted out of one of the swells and across my mouth now it still feel as painful as before, please help me as i have a fear of dentist from when i was a child.

thank you
