Pain in the sternum can result from various causes, including musculoskeletal issues, heart conditions, digestive problems, or inflammation.
Understanding Sternum Pain: A Complex Symptom
The sternum, commonly known as the breastbone, sits right in the center of your chest. It’s a flat bone that connects to the ribs via cartilage, forming the front of the rib cage and protecting vital organs like the heart and lungs. Because it’s centrally located and connected to many structures, pain in this area can stem from a wide range of issues.
Pinpointing what causes pain in sternum requires looking at several potential sources. The pain might be sharp or dull, constant or intermittent. It could worsen with movement or breathing. Sometimes it radiates to other parts of the body such as the back, neck, or arms. Understanding these nuances helps narrow down the cause.
Musculoskeletal Causes of Sternum Pain
One of the most common reasons for pain in the sternum is musculoskeletal in origin. This includes injuries or inflammation affecting bones, joints, muscles, or cartilage around the chest area.
Costochondritis
Costochondritis is inflammation of the cartilage connecting ribs to the sternum. It often causes sharp or aching pain directly over the breastbone. The discomfort typically worsens with deep breaths, coughing, or physical activity.
This condition can arise from repetitive strain, trauma to the chest (like a blow during sports), or even viral infections. Although alarming due to its chest location, costochondritis is generally benign and resolves with rest and anti-inflammatory medication.
Muscle Strain
Straining chest muscles during heavy lifting or intense exercise can cause localized sternum pain. Muscle strain often feels tender when pressing on affected areas and may increase with movement involving those muscles.
People who engage in activities requiring repetitive upper body motion—such as swimming or weightlifting—are particularly prone to this type of pain.
Sternal Fractures and Injuries
Trauma such as car accidents or falls can fracture the sternum. This leads to severe pain exacerbated by breathing and movement. Sternal fractures may also cause bruising and swelling around the chest.
Though less common than rib fractures, sternal injuries need medical evaluation because they might accompany internal organ damage.
Cardiac-Related Sternum Pain
Pain behind or near the sternum raises immediate concerns about heart-related problems. While not all chest pain signals cardiac issues, some conditions require urgent attention.
Angina Pectoris
Angina occurs when heart muscles don’t get enough oxygen-rich blood due to narrowed coronary arteries. This leads to pressure-like chest pain that often feels like squeezing under the sternum.
The discomfort usually lasts a few minutes and may spread to shoulders, arms, jaw, or back. Physical exertion or emotional stress often triggers angina.
Myocardial Infarction (Heart Attack)
A heart attack causes sudden blockage of blood flow to part of the heart muscle. The resulting ischemia produces intense chest pain beneath or around the sternum that lasts longer than angina and doesn’t improve with rest.
Additional symptoms include sweating, nausea, shortness of breath, and dizziness. Immediate emergency care is critical for survival.
Pericarditis
Pericarditis is inflammation of the pericardium—the sac surrounding the heart. It causes sharp stabbing pain that worsens when lying down or taking deep breaths but improves when sitting up and leaning forward.
Viral infections are a common cause; sometimes it follows a heart attack or surgery.
Gastrointestinal Triggers for Sternum Pain
Digestive system issues can mimic cardiac symptoms by causing discomfort near or behind the sternum.
Gastroesophageal Reflux Disease (GERD)
GERD results from stomach acid flowing back into the esophagus due to a weak lower esophageal sphincter. This acid reflux irritates esophageal lining causing burning chest pain (heartburn) often felt behind the breastbone.
The sensation typically worsens after meals or when lying down and may be accompanied by a sour taste in the mouth.
Esophageal Spasms
Uncoordinated contractions of esophageal muscles cause sudden squeezing chest pain resembling angina but unrelated to heart disease. These spasms can last minutes and sometimes trigger difficulty swallowing.
Stress and GERD are known triggers for esophageal spasms.
Peptic Ulcers
Ulcers developing in stomach lining or upper small intestine may cause gnawing epigastric pain radiating toward the sternum area. Eating might relieve or worsen this discomfort depending on ulcer location.
Bleeding ulcers require prompt medical attention due to risk of serious complications.
Inflammatory Conditions Affecting Sternum
Certain inflammatory disorders target joints around the sternum causing persistent pain and tenderness.
Sternoclavicular Joint Arthritis
This joint connects your collarbone (clavicle) to your sternum. Arthritis here leads to localized swelling and aching over upper breastbone region which intensifies with arm movement.
Both osteoarthritis (wear-and-tear) and rheumatoid arthritis (autoimmune) can affect this joint.
Tietze Syndrome
Similar to costochondritis but rarer, Tietze syndrome involves swelling along with inflammation at rib-sternum junctions causing sharp localized tenderness over one side of sternum accompanied by visible swelling on examination.
It tends to affect younger adults without clear injury history.
Nerve-Related Causes Behind Sternum Pain
Nerves supplying sensation around your chest can become irritated leading to neuropathic-type pain centered near your sternum area.
Intercostal Neuralgia
Irritation or damage to intercostal nerves running between ribs produces sharp burning or shooting pains along rib cage including near sternum region. Causes include trauma, shingles infection (herpes zoster), or nerve compression from spinal problems like herniated discs.
This nerve pain often worsens with movement or deep breathing making everyday activities uncomfortable.
Other Less Common Causes Affecting Sternum Region
- Pulmonary Embolism: A blood clot blocking lung arteries causes sudden severe chest pain under sternum along with shortness of breath.
- Aortic Dissection: A tear in aorta wall leads to tearing chest pain radiating from sternum toward back; an emergency condition.
- Mediastinitis: Infection within mediastinum (central chest cavity) after surgery/injury causes severe sternal tenderness plus fever.
- Anxiety/Panic Attacks: Intense episodes trigger chest tightness mimicking cardiac symptoms but without physical damage.
Sternum Pain Characteristics Table: Common Causes & Symptoms
| Cause | Pain Description | Associated Symptoms |
|---|---|---|
| Costochondritis | Aching/sharp; worsens with deep breath & movement | Tenderness over cartilage; no systemic signs |
| Angina Pectoris | Squeezing/pressure under sternum lasting minutes | Radiates arm/jaw; triggered by exertion/stress |
| GERD (Acid Reflux) | Burning behind breastbone after meals/lying down | Sour taste; regurgitation; cough at night |
| Sternal Fracture | Severe sharp pain aggravated by breathing/movement | Bruising/swelling; history of trauma impact/chest injury |
| Tietze Syndrome | Sharp localized tenderness with visible swelling on one side | No systemic illness; young adults mostly affected |
The Diagnostic Approach for Sternum Pain
Figuring out what causes pain in sternum starts with detailed history-taking—understanding onset timing, character of pain, triggers, associated symptoms like breathlessness or fever—and physical examination focusing on tenderness points and signs of trauma/inflammation.
Diagnostic tests play a crucial role:
- Electrocardiogram (ECG): Screens for cardiac ischemia.
- X-rays: Identify fractures/inflammation.
- Echocardiogram: Assesses heart function/pericardial disease.
- Barium swallow/endoscopy: Evaluates GERD/esophageal pathology.
- MRI/CT scans: Detect soft tissue injury/inflammation.
Lab tests including cardiac enzymes help rule out myocardial infarction while inflammatory markers indicate arthritis/infections.
Early diagnosis is key especially for life-threatening conditions like heart attacks or pulmonary embolism.
Treatment Strategies Based on Cause of Sternum Pain
Treatment varies widely depending on underlying cause:
- Musculoskeletal Issues: Rest combined with NSAIDs reduces inflammation; physical therapy aids muscle recovery.
- CARDIAC CONDITIONS: Angina requires medications like nitrates/beta-blockers plus lifestyle changes; myocardial infarction demands emergency intervention including thrombolysis/stenting.
- DIGESTIVE CAUSES: GERD improves with proton pump inhibitors/dietary modifications.
- AUTOIMMUNE/INFLAMMATORY DISORDERS: Corticosteroids/immunosuppressants help control joint inflammation.
Ignoring persistent sternal pain risks worsening outcomes especially if related to heart disease.
Lifestyle Tips To Prevent Recurring Sternum Pain Episodes
Small changes can make a big difference:
- Avoid heavy lifting without proper technique.
- If you smoke—quit immediately as it exacerbates GERD and cardiovascular risk.
- Avoid large meals before bedtime if prone to acid reflux.
- Add regular moderate exercise but avoid sudden strenuous activity without warming up.
- If anxiety triggers your symptoms practice relaxation techniques including deep breathing exercises.
Maintaining overall cardiovascular health through balanced diet rich in fruits/vegetables plus regular check-ups reduces chances of serious cardiac causes presenting as sternal discomfort.
