What Causes Pain in the Chest Bone?

The bone located in the center of the chest is commonly referred to as the sternum. The upper, central portion of the sternum is called the manubrium, while multiple ribs extend laterally from both sides of the sternum. The portions of the ribs that connect to the sternum consist of costal cartilages. So, what causes pain in the chest bones? Below, we provide an explanation.

What Causes Pain in the Chest Bones?

1. Fracture

Pain in the ribs may result from direct trauma—such as impact or a motor vehicle accident—often accompanied by restricted movement. In such cases, prompt medical evaluation is essential to assess the number and severity of rib fractures. Treatment primarily involves bed rest; when ambulating, a rib stabilizing brace should be worn to protect the fractured area.

2. Costochondritis

Costochondritis typically occurs during periods of physical overexertion, reduced immunity, or inadequate rest. Prolonged strain or exposure to cold may trigger an aseptic inflammatory response in the costal cartilages, leading to chest wall pain. Symptomatic relief can often be achieved through traditional Chinese medicine (TCM) topical applications and other physical therapies.

3. Cardiac Conditions

If chest bone pain occurs without preceding trauma or signs of inflammation, cardiovascular disease—such as coronary artery disease or angina pectoris—should be considered. Patients experiencing such pain are advised to seek timely evaluation at a reputable hospital for comprehensive diagnostic testing and condition-specific treatment.

4. Psychological Factors

Emotional stress—including anger, anxiety, fatigue, or insomnia—can also manifest as chest discomfort. This type of pain is generally not indicative of a serious underlying medical condition and may resolve with self-regulation and stress management.

The above outlines common causes of chest bone pain. We hope this information is helpful to you.
