Sternum pain can stem from cardiac, musculoskeletal, gastrointestinal, or respiratory issues, requiring careful evaluation for accurate diagnosis.
Understanding Sternum Pain: A Complex Symptom
Sternum pain isn’t just a simple ache in the chest; it can signal a variety of underlying conditions ranging from harmless muscle strain to life-threatening heart problems. The sternum, also known as the breastbone, is a flat bone located at the center of the chest that connects to the ribs via cartilage. This central position means any discomfort in this area can originate from multiple systems—cardiac, respiratory, gastrointestinal, or musculoskeletal.
Pinpointing what would cause sternum pain requires a thorough understanding of the potential sources and their characteristics. The quality, duration, and triggers of the pain provide essential clues. For instance, sharp pain that worsens with deep breaths might indicate a lung issue, while pressure-like discomfort could suggest cardiac involvement.
Cardiac Causes: When Sternum Pain Signals Heart Trouble
One of the most alarming reasons for sternum pain is heart-related conditions. Angina pectoris and myocardial infarction (heart attack) are prime examples where sternum pain demands immediate medical attention.
Angina occurs when the heart muscle doesn’t get enough oxygen-rich blood due to narrowed coronary arteries. This typically causes a pressing or squeezing sensation behind the sternum that may radiate to the jaw, neck, or arms. It often appears during physical exertion or stress and subsides with rest.
A myocardial infarction happens when a coronary artery is blocked completely. The sternum pain in this case is intense, persistent, and may be accompanied by sweating, nausea, shortness of breath, and dizziness.
Other cardiac causes include pericarditis (inflammation of the sac surrounding the heart), which often causes sharp pain aggravated by lying down or deep breathing.
Key Cardiac Symptoms Associated with Sternum Pain:
- Pressure-like or squeezing sensation
- Pain radiating to arms or jaw
- Shortness of breath
- Cold sweats and nausea
- Palpitations or irregular heartbeat
Musculoskeletal Factors: The Most Common Culprits
Muscle strain and inflammation around the chest wall are frequent causes of sternum pain that are often overlooked. Costochondritis—the inflammation of cartilage connecting ribs to the sternum—is a classic example.
Costochondritis usually presents as localized tenderness over the sternum that worsens with movement or deep breathing. It’s common among athletes who engage in repetitive upper body activities or after trauma such as heavy lifting or impact injuries.
Other musculoskeletal causes include:
- Sternoclavicular joint arthritis or injury
- Muscle spasms in chest muscles like pectoralis major
- Rib fractures near the sternum
These conditions typically cause sharp or aching pain that intensifies with physical activity but improves with rest and anti-inflammatory treatments.
Distinguishing Musculoskeletal Pain from Cardiac Pain:
Musculoskeletal pain usually:
- Is reproducible by pressing on the sternum area
- Worsens with movement or certain postures
- Lacks radiation to other body parts
- Is not accompanied by systemic symptoms like sweating or breathlessness
Gastrointestinal Sources: When Digestion Hurts Your Chest
The esophagus lies just behind the sternum and can cause chest discomfort mimicking heart pain. Gastroesophageal reflux disease (GERD) is a common offender here.
GERD occurs when stomach acid refluxes into the esophagus causing burning chest pain known as heartburn. This sensation often worsens after meals or when lying down and may be accompanied by regurgitation and sour taste in the mouth.
Esophageal spasms can cause intense episodic chest pain resembling angina but without any cardiac origin. Similarly, esophagitis (inflammation) due to infections or medications can provoke sternum discomfort.
Peptic ulcers located high in the stomach near the esophageal junction may also cause referred pain behind the sternum.
Symptoms Suggesting Gastrointestinal Origin:
- Burning sensation behind sternum after eating
- Dysphagia (difficulty swallowing)
- Sour taste or regurgitation
- Pain relieved by antacids
- Episodic sharp pains linked to swallowing difficulty
Respiratory Causes: Lung-Related Sternum Pain Triggers
Lung conditions adjacent to the sternum can also produce chest discomfort. Pleuritis (inflammation of lung lining) often results in sharp stabbing pains that worsen with deep breaths or coughing.
Pneumonia involving anterior lung segments near the sternum may cause localized tenderness combined with fever and cough.
Pulmonary embolism—a blood clot blocking lung arteries—can cause sudden severe chest pain along with shortness of breath and rapid heartbeat. Though less common than cardiac causes, it’s an emergency condition requiring immediate attention.
Other respiratory contributors include bronchitis and asthma exacerbations where chest tightness is prominent but usually accompanied by wheezing and cough rather than isolated sternal pain.
Signs Indicating Respiratory-Related Sternum Pain:
- Pain worsening on deep inhalation or coughing
- Cough producing sputum or blood-tinged mucus
- Fever and chills if infection present
- Shortness of breath disproportionate to exertion level
- Tachycardia (fast heart rate)
A Closer Look at Trauma-Induced Sternum Pain
Direct trauma remains a frequent source of sternal discomfort. Car accidents causing “seatbelt syndrome” often lead to bruising, fractures, or dislocations involving the sternum and ribs.
Sternal fractures cause severe localized tenderness that worsens with movement and breathing. They may also impair respiratory function due to associated rib injuries.
Blunt trauma from sports injuries can result in contusions affecting muscles around the breastbone leading to persistent soreness lasting weeks if untreated properly.
Treatment Considerations for Trauma-Related Pain:
- Pain control using analgesics like NSAIDs or acetaminophen
- Rest and avoidance of strenuous upper body movements initially
- X-rays or CT scans for fracture confirmation if needed
- Physical therapy once acute phase resolves to restore mobility safely
The Role of Infections Causing Sternum Pain: Osteomyelitis & Beyond
Though rare, infections involving bones such as osteomyelitis of the sternum can lead to persistent sternal pain accompanied by swelling and redness overlying skin changes.
Post-surgical infections following procedures like open-heart surgery may also manifest as localized sternal discomfort combined with fever and drainage if abscess forms beneath surgical scars.
Tuberculosis affecting thoracic bones represents another infectious etiology requiring prolonged antibiotic therapy under specialist care.

Diagnosing what would cause sternum pain involves detailed history taking followed by targeted physical examination focusing on tenderness points, characterizing radiation patterns, associated symptoms like breathlessness, sweating, digestive complaints, etc.
Common diagnostic tools include:
- Electrocardiogram (ECG) for detecting cardiac ischemia/infarction signs;
- Chest X-ray assessing lung fields/rib fractures;
- Blood tests measuring cardiac enzymes indicating heart muscle damage;
- Endoscopy for suspected GERD/esophageal issues;
- CT scan/MRI providing detailed views in complex cases;
- Ultrasound-guided evaluation for soft tissue infections/inflammation.
Prompt diagnosis is critical especially when life-threatening conditions such as myocardial infarction or pulmonary embolism are suspected. In less urgent cases like costochondritis treatment trials based on clinical presentation suffice before advanced imaging is considered.
Treatment Strategies Tailored to Cause Type
Treatment varies widely depending on what would cause sternum pain:
– Cardiac Issues: Immediate hospitalization might be necessary for heart attacks including thrombolysis/stenting procedures alongside long-term medications such as beta-blockers/statins plus lifestyle adjustments focusing on diet/exercise cessation smoking.
– Musculoskeletal Conditions: NSAIDs remain first-line agents supplemented by physical therapy emphasizing gentle stretching & strengthening exercises.
– Gastrointestinal Problems: Proton pump inhibitors reduce acid production while dietary avoidance prevents symptom flare-ups.
– Respiratory Causes: Antibiotics treat infections whereas anticoagulants address clots.
– Trauma: Adequate analgesia combined with rest promotes healing.
– Infections: Prolonged antibiotic courses tailored per culture results are essential.Ignoring persistent sternal discomfort risks progression into chronic problems impacting quality of life significantly so timely medical consultation cannot be overstated.
