Well, I can tell you, a hurt shoulder isnt too bad, especially if you skii or do sports that use your legs mainly often. Believe me, ive screwed up both of knees and my back and since I skate every day, its not very fun >.< ive also sprained both my wrists, dislocated a shoulder, and have alot of stitches from various things, like skateboarding...biking...and skating XD. So just think yourself lucky, and you can use your hurt shoulder to get a cute girl to give you a massage

just say "man, my shoulder hurts...are you any good at massaging?"
