I broke my arm right below the shoulder a few yearsback (snowboarding), it was pretty nasty. Completlely seperated the bone, and dislocated my shoulder, and to make matters worse my shoulder muslce was all tangled int he break. So i went to the hospitaland they said it was "dislocated" and put it back in place. A week of excruciating pain (and a developing Oxy addiction) later, they calle dme up and said I needed to come in for "Emergancy sugery".

Long story short, because of the delayed reponse, I no longer have a left-front shoulder muscle.
