Sternum pain can result from injuries, inflammation, heart or lung issues, and digestive problems affecting the chest area.
Understanding Sternum Pain: The Basics
The sternum, or breastbone, is a flat bone located at the center of the chest. It connects to the ribs via cartilage and helps protect vital organs like the heart and lungs. Pain in this area can be alarming because it lies close to critical structures. But sternum pain doesn’t always signal a heart attack or life-threatening condition. The causes range from minor injuries to serious medical issues.
Sternum pain often presents as sharp, dull, burning, or pressure-like sensations. It can worsen with movement, deep breathing, or pressure on the chest bone. Pinpointing the exact cause requires understanding the wide variety of potential problems that can affect this central chest area.
Musculoskeletal Causes of Sternum Pain
One of the most common reasons for sternum pain lies within the musculoskeletal system. This includes bones, joints, muscles, and cartilage around the chest.
Costochondritis: Inflammation of Rib Cartilage
Costochondritis is an inflammation of the cartilage connecting ribs to the sternum. It often causes sharp or aching pain around the breastbone that worsens with movement or pressure. This condition may result from repetitive strain, heavy lifting, coughing spells, or minor trauma.
People with costochondritis usually experience tenderness when pressing on specific points along the sternum-rib junctions. The pain might mimic heart-related discomfort but is typically reproducible with palpation.
Muscle Strain and Injury
Straining chest muscles during exercise or sudden movements can cause localized sternum pain. Overuse injuries from activities like weightlifting or sports can inflame muscles attached near the breastbone. Direct trauma such as a blow to the chest also leads to bruising and soreness in this region.
Muscle-related sternum pain usually improves with rest and gentle stretching but may persist if aggravating activities continue.
Sternal Fractures and Trauma
Though rare compared to rib fractures, sternal fractures occur mainly due to blunt force trauma—car accidents being a common example. A fractured sternum causes intense localized pain that worsens with breathing or movement. Swelling and bruising over the breastbone are typical signs.
Immediate medical evaluation is necessary for suspected fractures due to risks of injury to underlying organs.
Cardiac Causes Linked to Sternum Pain
The heart lies just beneath the sternum’s left side, so certain cardiac conditions can manifest as sternum pain or discomfort.
Angina Pectoris: Reduced Heart Blood Flow
Angina occurs when coronary arteries narrow, limiting oxygen supply to heart muscle during exertion or stress. Patients describe angina as pressure, tightness, squeezing, or burning sensation behind the sternum that may radiate to arms or jaw.
This type of sternum pain typically lasts a few minutes and eases with rest or nitroglycerin medication. Angina signals underlying coronary artery disease requiring prompt medical attention.
Myocardial Infarction (Heart Attack)
A heart attack results from complete blockage of blood flow to part of the heart muscle causing tissue damage. Severe crushing chest pain centered behind the sternum is a hallmark symptom along with sweating, nausea, shortness of breath, and anxiety.
Unlike angina, this pain lasts longer and does not improve with rest. Immediate emergency care is crucial in suspected heart attacks.
Pericarditis: Inflammation Around Heart
Pericarditis refers to inflammation of the pericardium—the sac surrounding the heart. It causes sharp stabbing chest pain often felt behind or near the sternum that worsens when lying down or taking deep breaths.
Patients may notice relief by sitting up and leaning forward. Pericarditis can result from infections, autoimmune diseases, or post-heart attack complications.
Pulmonary Causes Affecting Sternum Area
Lung-related problems also frequently cause sternum region discomfort due to their proximity beneath the breastbone.
Pleurisy: Inflamed Lung Lining
Pleurisy involves inflammation of pleura—the membranes covering lungs and lining chest cavity. It produces sharp stabbing chest pain worsened by deep breathing, coughing, or sneezing near the sternum area if front lung surfaces are involved.
Infections like pneumonia commonly trigger pleurisy symptoms alongside fever and cough.
Pulmonary Embolism (PE)
A pulmonary embolism occurs when a blood clot blocks an artery in lungs causing sudden sharp chest pain often felt around or under the sternum along with shortness of breath and rapid heartbeat.
PE is life-threatening and demands urgent diagnosis through imaging tests such as CT pulmonary angiography followed by anticoagulant treatment.
Lung Infections and Tumors
Infections such as pneumonia can cause generalized chest discomfort including near the breastbone accompanied by cough and fever. Lung tumors pressing on nearby structures may also produce persistent dull ache referred around sternum area depending on tumor location.
Gastrointestinal Causes Behind Sternum Pain
Not all chest pains originate in thoracic structures; many stem from digestive organs situated just below or behind the breastbone.
Gastroesophageal Reflux Disease (GERD)
GERD happens when stomach acid flows back into esophagus irritating its lining causing burning sensation called heartburn centered behind lower part of sternum. This pain often worsens after meals or lying down flat at night.
GERD-related discomfort sometimes mimics cardiac angina but usually responds well to antacids and lifestyle changes like avoiding spicy foods and elevating head during sleep.
Esophageal Spasms
Esophageal spasms involve sudden contractions of esophageal muscles producing intense squeezing chest pain resembling angina located behind breastbone lasting minutes at a time. Triggers include swallowing hot/cold liquids or stress.
Diagnosis requires specialized tests such as esophageal manometry while treatment includes muscle relaxants and dietary modifications.
Hiatal Hernia
A hiatal hernia occurs when part of stomach pushes through diaphragm opening into chest cavity causing burning sensation behind sternum along with regurgitation symptoms similar to GERD.
Surgical repair might be necessary for large hernias causing persistent symptoms unresponsive to medical therapy.
Other Less Common but Important Causes
Anxiety and Panic Attacks
Anxiety disorders frequently cause chest tightness described as pressure behind breastbone accompanied by rapid heartbeat, sweating, dizziness—symptoms easily mistaken for cardiac events but originating from nervous system activation rather than physical injury.
Managing anxiety through counseling and medications often alleviates these symptoms effectively without invasive testing once cardiac causes are ruled out safely by physicians.
Shingles (Herpes Zoster)
Shingles infection reactivates dormant chickenpox virus affecting nerve roots supplying skin over chest leading to burning painful rash near sternum area before blisters appear which helps confirm diagnosis clinically.
Early antiviral treatment reduces severity while nerve pain may persist after rash resolution requiring specialized management strategies like neuropathic pain medications.
Sternum Pain Causes Comparison Table
| Cause Category | Common Symptoms | Treatment Approaches |
|---|---|---|
| Musculoskeletal (e.g., Costochondritis) | Pain worsening on movement/pressure; localized tenderness | Rest, NSAIDs, physical therapy |
| Cardiac (e.g., Angina) | Tightness/pressure behind sternum; radiates; exertion triggered | Nitroglycerin; lifestyle changes; cardiac procedures if needed |
| Pulmonary (e.g., Pleurisy) | Sharp stabbing pain with breathing/coughing; fever if infection present | Treat infection/inflammation; analgesics; anticoagulants for PE |
| Gastrointestinal (e.g., GERD) | Burning sensation after meals/lying down; acid taste in mouth | Diet modification; antacids; proton pump inhibitors (PPIs) |
The Diagnostic Journey for Sternum Pain
Accurately diagnosing what can cause sternum pain involves multiple steps because many conditions share similar symptoms yet differ vastly in severity. Doctors begin by taking a detailed history focusing on onset timing, character of pain, associated symptoms like shortness of breath or sweating, triggers such as exercise or meals, past medical history including cardiac risk factors.
Physical examination follows carefully checking for tenderness over ribs/sternum suggesting musculoskeletal origin versus signs pointing toward lung issues like abnormal breath sounds. Cardiac evaluation includes measuring vital signs plus ECG testing looking for ischemia patterns indicative of angina or myocardial infarction.
Imaging studies play a crucial role too:
- X-rays: Useful for detecting fractures.
- Echocardiogram: Assesses heart function.
- CT scans: Detect pulmonary embolism & lung pathology.
- Endoscopy: Evaluates esophagus/stomach in reflux cases.
Blood tests help identify infections (high white cells), inflammation markers (CRP), cardiac enzymes (troponins) confirming heart damage if present.
Treatment Strategies Based On Cause Specificity
Treatment always depends on identifying what exactly causes your sternum pain:
- If musculoskeletal: Resting activity that triggers symptoms plus anti-inflammatory medications usually resolves costochondritis within weeks.
- If cardiac: Emergency intervention might be needed for heart attacks while stable angina benefits from medications controlling blood flow plus lifestyle changes.
- If pulmonary:Pleurisy requires treating underlying infection/inflammation while pulmonary embolism demands immediate anticoagulation therapy.
- If gastrointestinal:Lifestyle modifications reducing acid reflux combined with medications like PPIs offer relief from GERD-induced discomfort.
- If anxiety-related:Cognitive behavioral therapy alongside anxiolytics helps manage panic-induced chest tightness effectively.
- If shingles:Acyclovir antivirals started early reduce severity plus neuropathic agents ease lingering nerve pains.
Avoiding Serious Complications Linked To Sternal Pain Causes
Ignoring persistent sternal discomfort could lead to dangerous outcomes especially if caused by cardiac events like myocardial infarction where delay increases death risk significantly.
Similarly untreated pulmonary embolism may result in respiratory failure while chronic untreated GERD risks esophageal damage including Barrett’s esophagus—a precancerous condition.
Therefore prompt evaluation ensures timely management preventing complications.
The Role Of Lifestyle And Prevention In Sternal Pain Management
Certain lifestyle habits influence many causes linked with sternum pain:
- Avoid smoking which increases cardiovascular & lung disease risks dramatically.
- Keeps active but avoid heavy lifting without proper technique reducing musculoskeletal injuries.
- A balanced diet low in fatty/spicy foods prevents acid reflux flare-ups.
- Mental health care reduces anxiety/panic episodes manifesting as chest tightness.
- Masks & hygiene practices lower respiratory infections that could trigger pleurisy/shingles outbreaks.
- Minding posture alleviates undue strain on chest wall muscles during daily activities/work.
Implementing these habits promotes overall thoracic health lowering chances of developing painful conditions around your breastbone.
