A sudden episode of chest pain can be deeply alarming. When breathing brings a sharp pain, it is natural to worry about a serious heart condition. However, costochondritis is one of the most common causes of chest pain, and in most cases, it is not a dangerous illness.
Costochondritis is a condition caused by inflammation in the cartilage connecting the ribs and the sternum. Specifically, inflammation develops at the costochondral junction or sternochondral junction, causing notable discomfort characterized by distinct tenderness when the area is pressed. Because it frequently occurs on the left side of the chest, it is easily mistaken for cardiac pain. However, costochondritis typically worsens with movement or certain postures, and brings a sharp, stinging sensation during deep inhalation.
Why does costochondritis develop? In most cases, no clear cause can be identified. Nevertheless, it may arise after excessive coughing or sneezing, physical strain from repeatedly lifting heavy objects, direct trauma to the chest, or an inflammatory reaction following an upper respiratory tract infection. It can also appear as part of a generalized pain condition like fibromyalgia, and on rare occasions, it may be associated with chest wall tumors or arthritis.
Diagnosis is primarily made through clinical history and a physical examination. The most critical step is ruling out severe conditions such as myocardial infarction, angina pectoris, pneumonia, pneumothorax, herpes zoster, and breast cancer. A clinic will generally perform tests such as an electrocardiogram examination, chest x-ray, and blood test to confirm that no other conditions are present. If these tests return normal and distinct tenderness is found at a specific site, costochondritis is considered very likely.
Costochondritis usually resolves on its own over time. However, if the pain interferes with daily activities or causes significant worry, appropriate management is helpful. Relieving inflammation involves using an anti-inflammatory analgesic, applying a warm compress or cold compress, and getting adequate rest. Stress can also tighten the chest muscles and lower the pain threshold, so easing mental strain—much like resolving the qi stagnation described in the Donguibogam—supports recovery. Because chest pain is an important physical signal, consulting a medical professional for an accurate evaluation is always recommended.
