I pitched a while. But it came from dodgeball. Was playing a f***ing intense game of dodgeball, put everything I had into a throw, nailed a kid whom I hated in the face (I had pretty good accuracy), felt something pop, and my arm went dead. It's slightly less serious than what Dustin McGowan had - elbow tendinitis, torn rotator cuff, and shoulder inflammation. ~10 weeks of physio. Not fun, lol.
