What Is Sternum Popping?
Sternum popping refers to a cracking or clicking sound that occurs in the chest, typically near the breastbone. It often happens during stretching, deep breathing, or twisting movements. While it can feel unusual or alarming, most cases are harmless and caused by natural joint or cartilage movement.
Common Causes of Sternum Clicking and Popping
- Joint Movement or Pressure Release
Gas buildup in the joints can release during motion, producing a harmless popping noise. This is similar to cracking your knuckles and is usually not a cause for concern. - Muscle Strain or Tension
Overuse, poor posture, or tight chest and back muscles can pull on the joints around the sternum, resulting in a popping sensation during certain movements. - Costochondritis
This condition involves inflammation of the cartilage that connects your ribs to your sternum. It can cause localized chest pain and occasional popping during movement or deep breathing. - Slipping Rib Syndrome
Lower ribs may become loose and slip under surrounding muscles or tissue, creating a sharp popping sound. This condition often causes discomfort or sharp pain during motion. - Sternoclavicular Joint Instability
This joint connects the collarbone to the sternum. If it becomes unstable or inflamed, it may click or pop when you move your shoulders or arms. - Trauma or Injury
Any direct blow or impact to the chest may cause damage to the cartilage or ribs, potentially leading to sternum popping. Fractures or dislocations can also result in audible clicks or pain. - Post-Surgical Recovery
Popping may occur during healing from chest surgeries, such as open-heart procedures. While some movement is normal, consistent or painful popping could indicate complications.
Symptoms That May Accompany Sternum Popping
- Audible popping or cracking noise when moving or stretching
- Mild soreness or tightness in the chest
- Sharp pain during breathing, twisting, or lifting
- Swelling or tenderness around the sternum
- Pain that radiates into the shoulders, back, or abdomen
- Discomfort when lying down or applying pressure to the chest
Sternum Popping? When to See a Doctor
Most cases of sternum popping are not serious. However, you should seek medical attention if you experience:
- Persistent or worsening chest pain
- Swelling, bruising, or visible deformities in the chest
- Difficulty breathing or tightness in the chest
- Popping sounds following recent chest trauma or surgery
- Pressure-like chest pain, especially on the left side
- Pain that radiates into the arm, jaw, or upper back
How Sternum Popping Is Diagnosed
To identify the cause, a healthcare provider may:
- Review your medical history and symptoms
- Perform a physical exam to pinpoint the source of pain or popping
- Order imaging tests such as X-rays, ultrasounds, or MRIs
- Recommend additional cardiac testing if heart-related symptoms are suspected
Treatment Options
Home Remedies and Self-Care for a popping sternum
- Rest and avoid triggering movements
- Apply heat or cold packs to reduce tension and inflammation
- Use over-the-counter medications such as ibuprofen or acetaminophen
- Practice proper posture to avoid joint and muscle imbalances
- Perform light stretching and mobility exercises
Physical Therapy
A physical therapist can guide you through stretches and exercises that strengthen the chest, back, and shoulder muscles—helping to improve joint stability and reduce popping.
Medical Treatments
For more serious or persistent cases, medical options may include:
- Corticosteroid injections to reduce inflammation
- Surgical repair in cases of joint damage, rib instability, or sternal separation
- Treatment for underlying conditions such as arthritis or chronic inflammation

- Stretch your chest, shoulders, and back regularly
- Avoid repetitive stress or overuse of the upper body
- Address pain early to prevent joint instability or worsening symptoms
- Manage stress levels to reduce muscle tension in the chest area
Frequently Asked Questions (FAQ)
Is sternum popping dangerous?
Usually not. If it’s occasional and not painful, it’s often just natural joint movement. However, persistent or painful popping should be checked by a medical professional.
Can anxiety make sternum popping worse?
Yes. Stress and anxiety can cause muscle tension, especially in the chest, which may increase awareness of discomfort or lead to more frequent popping.
Is sternum popping related to heart problems?
Not directly. Most sternum popping is musculoskeletal. But any chest pain that feels like pressure or is accompanied by shortness of breath should be evaluated urgently.
Can stretching fix the issue?
Gentle stretching and strengthening exercises can help correct muscle imbalances and reduce pressure around the sternum. Avoid aggressive movements unless guided by a professional.
How long does recovery take?
Recovery time varies. Mild muscle strains may resolve in a few days, while more serious issues—like rib injuries or post-surgical recovery—may take weeks or even months.
What if it happens after surgery?
Some popping is normal as the sternum heals. However, if it becomes frequent, painful, or feels unstable, it’s important to contact your surgeon.
Final Thoughts
Sternum popping is a common and often harmless experience linked to movement in the joints or cartilage of the chest. While it typically isn’t a cause for concern, it’s important to monitor symptoms—especially if the popping is accompanied by pain, swelling, or difficulty breathing. Focus on maintaining good posture, incorporating mobility exercises, and seeking medical guidance when needed. Your chest should move—just make sure it moves safely.
