What to do if arm is bruised and swollen do to a fall?

If your arm is bruised and swollen after a fall, first rest the arm and avoid using it to prevent further injury. Apply ice wrapped in a cloth for 15-20 minutes every hour to reduce swelling and pain. Elevate the arm above heart level to help decrease swelling. If the pain persists or if there is severe swelling, deformity, or inability to move the arm, seek medical attention to rule out fractures or more serious injuries.
