Your rib cage includes both bone and cartilage, a firm tissue that is more elastic than bone. Cartilage attached to the front portion of your ribs allows your chest to expand as you move and breathe. Both your ribs and the associated pieces of cartilage have limited flexibility. Trauma or overstretching the junction between the bones and cartilage of the rib cage can cause a tear. Pain is the predominant symptom. Seek medical attention if you suspect a torn rib cartilage as there may be additional damage to your rib cage or internal organs.
Torn cartilage in the ribs is usually very painful. Sharp pain typically occurs immediately at the site of the tear. Ongoing pain may persist for weeks to months, depending on the severity of the injury. Your doctor may recommend an over-the-counter or prescription pain reliever to reduce your discomfort. In some cases, doctors inject anti-inflammatory and pain-relieving medications directly into the injured area. For the first few days after the injury, applying a cold pack for 15 minutes every 3 to 4 hours may help reduce the pain. After 72 hours, heat may be applied for 15 to 20 minutes every few hours to promote healing by increasing blood flow in the affected area.
The diaphragm -- the main muscle used for breathing -- attaches to your lower ribs. As a result, simple movements such as breathing, coughing or sneezing may provoke or increase pain caused by a rib cartilage tear. Other everyday movements that involve twisting or expansion of your rib cage may also cause pain. Holding a pillow against your chest may make these movements less painful. Your doctor may advise you to see a physical therapist, who can instruct you how to move and gradually return to normal activity without aggravating your symptoms.
Bruising is likely in the affected area if a rib cartilage tear occurred due to a forceful blow to your chest. Swelling is also common at the site of the injury. You may notice clicking, popping or grinding at the site of the tear, especially when you take a deep breath. Your breathing may be slightly more shallow than normal as you instinctively try to minimize your pain by avoiding deep breathing.
Injuries to your rib cage can be serious, so it's important to see a doctor if you sustain any rib-related injury. Multiple ribs can be involved, which may jeopardize your ability to breathe. You also need to be examined to make sure your internal organs have not been injured. Additionally, heart disease can cause chest pain similar to that associated with a rib cartilage tear. Seek emergency medical care if you experience difficulty breathing or chest pain that is not associated with an injury -- especially if accompanied by sweating, nausea, dizziness, or arm or jaw pain.
