i'm kicking my ass! do you mind?

For some reason today I'm all about self inflicting pain on my jaw. This morning when I was brushing my teeth, I jabbed the damn toothbrush really hard into my gums or some tooth in the back of my mouth and the sh*t hurts. Not that gums or teeth are my "jaw" per se but it's in the same area. Then when I was at the gym on my lunch break today, I was adjusting my sports bra after I put it on (sorry for that visual) and punched myself in the chin. What the hell?
