First question, I snowboard, sometimes after a day of snowboarding (after taking a few hard slams usually on my back or side) I find that when I take in deep breaths, I get a weird pain under my right collar bone, maybe the top of my lung, what is this?

Second question, I rolled my ankle pretty bad in the summer, and it still hurts when I bend my ankle on some angles... Is it fractured? I can walk on it fine, but when im walkin up steep hills my ankle starts to crack almost directly in the middle of my foot and it hurts... If you think it could be broken, will it cause more damage to leave it? Or should I get it checked out, I really dont want to have to lose my snowboarding season to something I could have fixed months ago...
