A broken leg is an injury that occurs when one of the bones in the leg is fractured or cracked. This can happen due to accidents, falls, or sports injuries. When someone has a broken leg, they may experience pain, swelling, and difficulty walking. It often requires medical attention, and sometimes a cast or surgery is needed to help the bone heal properly. Recovery from a broken leg can take several weeks to months, depending on the severity of the injury. During this time, it's important to rest and follow a doctor's advice. Physical therapy may also be recommended to help regain strength and mobility in the leg after the bone has healed.
