Chest Pain Below The Breastbone: Possible Causes And Symptoms

If you experience pain in the area where the lower part of the sternum meets the left rib cage, it could be related to various health conditions. One of the most common and serious causes is angina pectoris associated with coronary artery disease. This type of chest discomfort often occurs during physical exertion, such as walking 100-500 meters, cycling, or climbing stairs. The pain may last only a few minutes and can radiate to the left arm, neck, or jaw, which are classic signs of angina.

Recognizing Angina Symptoms

One key characteristic of angina is that the discomfort typically subsides with rest or after using nitroglycerin or similar medications like quick-acting heart-saving pills. If your chest pain follows this pattern—triggered by activity and relieved by rest or medication—it's important to consider the possibility of underlying heart disease and consult a medical professional for proper evaluation.

Non-Cardiac Causes Of Chest Discomfort

Gastrointestinal Issues

Not all chest pain is related to the heart. Conditions affecting the digestive system can also cause discomfort in the chest area. For example, individuals with peptic ulcers, gastric spasms, or esophageal ulcers may notice pain that occurs either before or after eating. Some people find that their symptoms worsen after meals, while others experience temporary relief from pain when they eat, which can indicate gastrointestinal involvement.

Musculoskeletal Conditions

Less commonly, chest wall pain may be caused by musculoskeletal issues such as costochondritis (inflammation of the cartilage connecting the ribs to the sternum), rib fractures, or even tumors behind the sternum that involve the thymus gland. These conditions typically cause localized tenderness and pain that may worsen with movement or pressure on the affected area.

When To Seek Medical Attention

While not all chest pain is life-threatening, it's crucial to take any persistent or recurring discomfort seriously. If you experience chest pain that radiates to other areas of the upper body, shortness of breath, nausea, or dizziness, seek immediate medical attention. Even if your symptoms seem mild or intermittent, a proper diagnosis from a healthcare provider is essential to rule out serious conditions and begin appropriate treatment.
