Forehead split. Just had stitches. That one looked a lot worse than it really was cuz there was a lot of blood. Didn't hurt.
Got my leg sliced open. i was running and like i didn't even realize what happened till i felt something on my leg, looked down, i was leaking could see my bone and everything. Just got stitches on that too. i didn't even feel it.
Recently strained muscle in my back and that was bad. Felt like i would never be able to walk normal again. Healed in a couple weeks.
Most painful thing i ever felt was infected wisdom tooth. Hurt more then any purely physical pain could.
