A bone injury refers to any damage to the structure of a bone, which can occur due to trauma, overuse, or medical conditions. Common types of bone injuries include fractures, where the bone breaks, and sprains, which involve the ligaments around the bone. Symptoms often include pain, swelling, and difficulty moving the affected area. Treatment for bone injuries typically involves rest, ice, compression, and elevation, known as the RICE method. In more severe cases, medical intervention may be necessary, such as casting or surgery. Proper healing is essential to restore function and prevent complications.
