Intercostal muscles are thin muscles that attach between the ribs and help with breathing. They are divided into three layers: external, internal, and innermost intercostals. A strain in any of these layers can cause chest pain and difficulty breathing. Intercostal muscle strains are the most common type of musculoskeletal chest pain and can be caused by a sudden increase in activity or overuse. The pain can be sharp or dull and worsen with breathing, movement, coughing, or sneezing.

What You'll Learn
Intercostal muscle strain causes
Intercostal muscle strain is an injury to the intercostal muscles between the ribs. There are three layers of intercostal muscles: external, internal, and innermost. The external intercostal muscles are the outermost layer and run from the anterior to the posterior rib cage. They are responsible for the movement of the ribs during breathing and elevate the ribs during inspiration.
Intercostal muscle strain is almost always the result of some event, such as overexertion or injury. A sudden increase in physical activity can also lead to an intercostal muscle strain, especially if the individual has poor posture or weak muscles. Trauma to the chest, such as a fall or direct blow, can also cause intercostal muscle strain. Other causes include:
- Overuse or repetition, such as lifting heavy objects or participating in sports like golf or tennis
- Poor posture when standing or sitting for extended periods
- Weak and inadequately conditioned muscles, especially with activities like rowing, tennis, or batting
- Dehydration, which can lead to muscle fatigue and increase the risk of muscle strain
Intercostal muscle strain can cause pain and difficulty breathing. The pain can be sharp or dull and worsen with breathing, movement, coughing, or sneezing. There may also be muscle stiffness and tension, resulting in upper back pain and limited range of motion.

Differentiating intercostal pain from other conditions
Intercostal muscle strain can be differentiated from other conditions causing pain in the chest and/or ribs by assessing the type of injury, the precise location of pain, and whether the pain changes with physical activity.
Intercostal muscle strain is generally not very serious, but other forms of chest pain can be. It is advisable to seek medical attention to rule out other conditions and confirm that your chest pain is only due to a muscle injury.
Precise Location of Pain
Intercostal muscle strain results in localized pain and tenderness that increases with stretching or contraction of the intercostal muscles. The pain is typically felt between the ribs, indicating that it is not originating from the lungs or upper back.
Pain with Physical Activity
Intercostal muscle strain will result in increased pain with upper body movements. Other conditions, such as precordial catch syndrome and costochondritis, are more likely to cause pain with breathing. While costochondritis can be worsened by strenuous upper body movements, the pain is usually localized to the second through fifth ribs, where they join the sternum.
Pain Severity and Duration
Intercostal muscle strain can result in mild discomfort or severe symptoms. The pain may last for a prolonged period and may continue long after the initial injury has healed.
Other Symptoms
Intercostal neuralgia, a condition associated with intercostal muscle strain, can cause neuropathic pain throughout the rib cage and abdomen. This pain may be sharp, aching, radiating, burning, or stabbing, and may be accompanied by numbness and tingling.
Medical History and Examination
A diagnosis of intercostal muscle strain is made based on a patient's medical history and a physical examination. A neurological examination may be performed to screen for neurological issues, such as nerve root compression, which can also cause chest pain. Imaging techniques, such as a chest X-ray, may be used to rule out injuries to the lungs, ribs, or other structures in the chest.
It is important to seek medical attention if you are experiencing chest pain to ensure proper diagnosis and treatment.

Intercostal neuralgia
The treatment for intercostal neuralgia depends on the severity of symptoms, other medical issues, and patient preferences. Various treatments can be used alone or in combination to manage the pain. Over-the-counter topical treatments and antidepressants can be used to provide temporary pain relief. In severe cases, opioid-based medications such as opioid-aspirin or opioid-acetaminophen may be prescribed, but these are typically a last resort due to their side effects and potential for addiction.
Intercostal nerve block injections, which combine a local anesthetic with corticosteroids, can be used to reduce inflammation and relieve pain for several months. A thoracic epidural injection involves injecting anti-inflammatory medication into the area around the spinal cord. Pulsed radiofrequency is a minimally invasive procedure that uses an electrode needle to provide short-term pain relief. It is important to remain physically active during treatment to maintain muscle strength and health.

Exercises to reduce pain and improve mobility
Strains of the intercostal muscles, which lie between the ribs, are a common cause of chest pain. The intercostal muscles have three layers: external, internal, and innermost. A strain occurs when a muscle stretches, pulls, or is partially torn. This can happen due to a sudden increase in activity, twisting motions, or repetitive motions.
If you are experiencing chest pain, it is important to seek medical attention, especially if you heard a pop at the time of injury, are experiencing numbness or tingling, or cannot move the area where you are experiencing pain.
Once you have consulted a medical professional and received a diagnosis, they may recommend specific exercises to help reduce pain and improve mobility. Here are some general exercises that may be suggested:
Rest, Ice, Compression, and Elevation (R.I.C.E.)
In the acute phase of an injury, the R.I.C.E. method can be used to manage pain and inflammation. This involves resting the affected area, applying ice, using compression, and elevating the injured site.
Diaphragmatic Deep Breathing
Place one hand on your stomach and the other on your chest. Take a deep breath in, pushing your belly and hand outwards while minimizing the movement of your chest. This technique helps you focus on deep breathing, improving your diaphragm's function, the main inspiratory muscle.
Pec Stretch
Stand with your arms at 90 degrees, palms flat on the wall, and face towards a corner. Push your body into the corner while keeping your hands in the same position. You will feel a stretch across your upper arms, front shoulders, and chest.
Straight Arm Pec Stretch
Hook your fingers around a door frame or corner of a wall, and lean forward to create a stretch across your upper arm, front shoulder, and slightly into your chest. This exercise stretches the pectoral muscle, the largest muscle in the chest.
Mid-Scalene Sternocleidomastoid Stretch
Hook your fingers above your collarbone and gently side-bend your neck to the opposite side. Hold the stretch, and you should feel it at the front and side of your neck. This exercise improves neck mobility.
In addition to these targeted stretches, low-impact exercises such as walking, swimming, or stationary cycling can aid in maintaining overall fitness without compromising the healing process. It is also crucial to maintain proper nutrition and hydration, which play essential roles in supporting muscle recovery and overall well-being.

Intercostal muscle strain treatment options
Intercostal muscle strain refers to an injury affecting the muscles between two or more ribs. It may cause sharp, direct pain, stiffness, and mobility difficulties. This type of injury often results from overexertion or trauma during exercise, such as twisting while lifting weights, prolonged overhead reaching, or a direct blow to the ribs.
Treatment Options:
- Rest: Resting and limiting all physical activity for a few days to allow time for the muscle strain to recover is essential.
- Pain Management: Over-the-counter medications such as acetaminophen or ibuprofen can help reduce swelling and pain.
- Cold and Heat Therapy: Applying an ice pack or cold pack, followed by heat therapy, such as a warm bath, heating pads, or adhesive heat wraps, can aid in pain relief and reduce inflammation.
- Breathing Exercises: It is crucial to stop smoking and avoid secondhand smoke to prevent further respiratory problems. Breathing exercises, such as deep breathing and diaphragm breathing, can help expand the chest and work the intercostal muscles.
- Physical Therapy: Gentle physical therapy may be advised to stretch tender muscles and improve mobility. This includes specific stretches for the intercostal muscles and gradual progression towards more active exercises.
- Medical Intervention: In more severe cases, a doctor may prescribe muscle relaxants or injectable medications, such as corticosteroids and lidocaine, to reduce pain and swelling. It is important to seek medical attention if symptoms persist, worsen, or if there is difficulty breathing, as it could indicate a more serious condition or injury.
