Ribs are bones that form the rib cage, which protects the heart and lungs. They are connected to the spine at the back and to the breastbone at the front. If a rib is displaced, it can cause pain, difficulty breathing, and other problems.
There are a few different ways to pop a rib back into place. One common method is to have someone hold your shoulders while you lean forward and then twist your body to the side. Another method is to lie on your back and have someone push on your rib cage from the side. If you are unable to pop your rib back into place on your own, you should see a doctor.
