How long does a bone heal?

A few days ago I went sledding and I fell out of my sled and rolled pretty hard. Well I hit my shoulder and ever since that day my bone in my shoulder is killing me at first I thought it was bruised but as days go by it is hurting more and more. I can't pick up things. Unless it's super light and I don't have to use alot of force but even with light things it still hurts. Any tips for me?
