Sternum pain can have many causes, including joint strains, muscle injury, and acid reflux. Chest pains can also be a symptom of a heart attack, and you should not ignore them.
Your sternum, or breastbone, connects the two sides of your rib cage. It sits in front of many major organs in your chest and gut, including your heart, lungs, and stomach. As a result, many conditions that don’t necessarily have anything to do with your sternum may cause pain in your sternum and the surrounding area.
Sternum pain more commonly occurs due to your muscle, joint, or digestive problems than with your heart or the sternum itself.
Keep reading to learn the common reasons for sternum pain and when to see your doctor.
Symptoms of costochondritis include:
- sharp pains or aches on the side of your sternum area
- pain or discomfort in one or more ribs
- pain or discomfort that gets worse when you cough or breathe in deeply
Costochondritis doesn’t always have a specific cause, but it is often a result of:
- chest injuries
- muscle strains
- joint conditions such as osteoarthritis
- autoimmune conditions like rheumatoid arthritis and ankylosing spondylitis
While costochondritis isn’t a severe condition and shouldn’t cause concern, contact your doctor if the pain persists or if you have other symptoms that might indicate a more serious underlying condition.
Conditions or injuries to the muscles and bones around your sternum can also cause sternum pain, including:
- sternoclavicular joint injury
- collarbone (clavicle) injury
- surgery on the sternum (such as open heart surgery)
These aren’t the only musculoskeletal conditions that may hurt your sternum but are among the most common.
Your sternum sits right in front of several major digestive organs. Conditions that affect your esophagus, stomach, and intestines can cause pain radiating in the chest’s center.
Acid reflux is when stomach acid flows up into the esophagus and causes irritation and pain. People refer to this pain as heartburn and commonly experience it after eating.
Heartburn usually goes away without treatment after a short time. However, persistent acid reflux may indicate a chronic condition called gastroesophageal reflux disease.
Conditions that affect your lungs, windpipe (trachea), and other parts of your body that help you breathe can cause sternum pain.
Pleurisy happens when your pleura gets inflamed. The pleura comprises tissue within your chest cavity and around your lungs. In some cases, fluid can build up around this tissue. This is called pleural effusion.

- feeling like you can’t get enough air
- an abnormal cough
