The humerus is the large bone in your upper arm. You have a broken (fractured) humerus. These fractures are easily diagnosed with X-rays.
Simple fractures which will heal without disability are treated with simple immobilization. Immobilization means you will wear a cast, splint, or sling. You have a fracture which will do well with immobilization. The fracture will heal well simply by being held in a good position until it is stable enough to begin range of motion exercises. Do not take part in activities which would further injure your arm.

Put ice in a plastic bag.
Place a towel between your skin and the bag.
Leave the ice on for 15 to 20 minutes, 3 to 4 times a day.
