What Causes Pain Above the Chest?

Chest pain located just above the sternum—often described as discomfort or pressure in the upper chest, near the base of the neck or clavicular region—can arise from a wide spectrum of conditions, ranging from benign and self-limiting to life-threatening. Accurate localization, character, duration, and associated symptoms are critical for clinical differentiation.

Cardiac causes remain a primary concern, particularly in individuals with cardiovascular risk factors. While classic angina typically presents as substernal pressure radiating to the left arm or jaw, atypical presentations—including isolated upper sternal or supraclavicular discomfort—may occur, especially in women, older adults, or those with diabetes. Acute coronary syndrome must be ruled out promptly, particularly when pain is provoked by exertion, relieved by rest or nitroglycerin, or accompanied by diaphoresis, dyspnea, nausea, or lightheadedness.

Non-cardiac etiologies are common and diverse. Musculoskeletal sources—such as costochondritis, sternoclavicular joint inflammation, or myofascial strain—often produce sharp, reproducible tenderness on palpation and may worsen with movement or deep inspiration. Gastroesophageal reflux disease (GERD) and esophageal spasm can mimic cardiac pain, frequently presenting with burning or squeezing sensations that may localize to the upper retrosternal area and fluctuate with meals or posture. Respiratory causes—including pleuritis, early pneumonia, or mediastinal lymphadenopathy—may also refer pain to this region, often accompanied by cough, fever, or pleuritic breathing patterns.

Less common but important considerations include cervical spine pathology (e.g., C5–C7 radiculopathy), anxiety-related somatic manifestations, and, rarely, mediastinal tumors or thyroid disorders causing referred discomfort. A thorough history, physical examination—including careful palpation of the sternoclavicular joint and costochondral junctions—and targeted investigations (e.g., ECG, troponin, chest imaging, or endoscopy) are essential to guide diagnosis and management.

Any new, unexplained, or worsening upper chest pain warrants timely medical evaluation. Patients should seek immediate care if pain is severe, persistent, associated with systemic symptoms, or occurs at rest—especially in the presence of known heart disease or significant risk factors.
