Intercostal Muscle Strain: Symptoms, Causes and Treatments

Intercostal muscle strain is the result of an extreme movement or rapid twisting of the torso. The muscles involved are located between the ribs, which can be very painful and may lead people to thinking that they have broken their ribs. The most common cause of intercostal muscle strain is a rapid twist of the torso in sports like tennis and basketball. While a person can experience strain on any muscle in the body, strains in the chest area can be severely excruciating.

Intercostal muscle strains have three gradings:

  • Grade I Strain – It is a mild strain that damaged some of the muscle fibers. This usually heals within 2 to 3 weeks.
  • Grade II Strain – It is a moderate muscle strain that damaged the muscle fibers more extensively. The muscle in grade II strain is not fully ruptured and can heal within 3 to 6 weeks.
  • Grade III Strain – This severe injury occurs when the muscle is completely damaged or ruptured. It usually requires a surgical repair. Grade III strain can heal up to 3 months.

Symptoms of Intercostal Muscle Strain

The common symptom of intercostal muscle strain is pain in the side of the chest area, usually in the lower ribs. The stabbing pain that comes suddenly is described as sharp, accompanied by a pulling sensation. There are cases that the pain is experienced gradually.

In mild cases, the affected person can be allowed to continue with the day-to-day tasks as the pain is still bearable. However, the symptoms may get worse. In severe cases, the affected person and athletes have to stop from performing their activities for enough period of time until the muscle has completely recovered. The symptoms of intercostal muscle strain may include:

Pain

  • Sharp and stabbing pain
  • Tenderness when touching the ribs area
  • Constant and severe pain
  • Sudden tearing pain
  • Intensifies when moving, twisting, sneezing or coughing

Swelling and Tenderness

  • Injured parts are swollen
  • Swollen area is filled with blood (Hematoma)
  • Swollen ribs
  • Tenderness over the ribs
  • Bruising
  • Painful to get up or down from a chair
  • Pain when turning over in bed

Muscle Tightness

  • The muscles in chest wall feel tight
  • Difficulty moving the chest area as well as arms
  • Severe tightness in the injured area

An individual may also experience shortness of breath as the muscles feel too tight to let air in. Breathing becomes shallow and painful.

Causes of Intercostal Muscle Strain

The intercostal muscles are composed of many groups of muscles: internal intercostals muscles, external intercostals, subcostal muscles and transverse thoracic muscles. These muscles are located between the ribs. They are responsible for moving the chest up and down. It also functions in forming and stabilizing the chest walls. When the strain is mild or moderate, intercostal muscles commonly recovers for 4 to 6 weeks with proper physiotherapy. However, severe intercostal muscle strain will require a longer period before it recovers fully.

These are the most common causes of intercostal muscle strain.

1. Twisting the Upper Body

Sudden twisting of the upper body can strain the muscles. Overdoing it can also lead to intercostal muscle strain as it exerts too much pressure on the ribs. Some activities that can involve twisting the upper body are dance moves, yoga postures, wrestling, and other sports. Even turning around to check if someone or something is behind you can strain the intercostal muscles.

2. Improper Warm up Before Training or Exercising

Not all individuals warm up the proper way, which may lead to more harm than good. Not warming up properly can increase the chance of torn muscles, which can be very painful. It may also take months up to a year before it completely recovers.

It is important to protect your muscles. While many people believe that securing the body parts can prevent a torn muscle, the only way to avoid it is by performing proper warm ups.

3. Swinging the Arms with Force

Swinging the arms with extreme force can stretch the ribs towards the arms. This condition is worse than suddenly twisting the upper body. With excessive force, it can tear the muscles, which will take months up to a year to recover.

4. Direct Blow to the Chest Wall

A blow to the chest wall can also strain the intercostal muscles. This can occur while playing sports, car accidents, a fight, or injuries received while working. A direct strong impact to the chest area can also bruise the chest wall, ribs, and muscles (chest contusion).

5. Over Stretching

Stretching the muscles extremely can strain or rupture the intercostal muscles. Even when stretching gently, there is a chance to strain the muscles in your rubs. When the intercostal nerves get trapped between the muscles and ribs, it can lead to painful spasms, strain, and nerve pain.

Excessive training or repetitive movement can also strain the muscles.

6. Not Enough Time to Heal the Muscles

When the muscle fibers are damaged, it usually takes two to six weeks to heal. While the pain is still bearable, it is important to give your muscles enough time for full recovery. Using the muscles for daily activities, exercises, or sports can make the symptoms worse and may eventually lead to a complete muscle rupture.

7. Poor posture

Poor posture can strain the intercostal muscles and may cause them to become weak over time. It can also lead to chest, neck, and back pain. Not correcting the posture increases your risk to Sciatica or Piriformis Syndrome, Shoulder Impingement and knee pain.

Other causes of intercostal muscle strain are:

  • Presence or joint and muscle stiffness
  • Weakness and fatigue
  • Lower back injury

10 Treatments for Intercostal Muscle Strain

Here are the ways on how to treat mild to moderate intercostal muscle strain.

1. Rest

After an injury, rest your muscles and do not perform intense physical activities. Give your muscles enough time to recover completely. Do not twist your torso to protect your muscles from further injury.

2. Hot and Cold

The cold temperature of ice can reduce the pain and swelling. Apply an ice pack as soon as possible for ten to twenty minutes. Do not apply direct ice to the skin. Once the swelling disappears, you can apply heat compress to the area. Repeat this treatment three or more times a day to alleviate the inflammation fast.

3. Brace or Splint the Area

Wrap or compress the area to decrease the swelling. Do not wrap it tightly and make sure that you loosen the bandage if it is too tight. Do this treatment during the first couple of days.

4. Therapeutic Exercise

Gentle stretching can strengthen the muscles, such as side bends with a bit of rotation. Get moving when the pain subsides. Not moving your body and muscles can increase the risk of further complications, such as muscle wasting, deep vein thrombosis, and chest infections.

Therapeutic exercises can restore mobility, strengthen the muscles, and improve range of motion. It can also decrease the pressure on the neck, discs, and spinal joints.

5. Deep Breathing

Breathing can be painful due to chest and rib pain. This may result in pneumonia and can delay the healing process of the muscles due to lack of oxygen. To prevent this from happening, you will need to take deep breathing exercises.

  1. Slowly inhale and open the lungs as much as possible.
  2. Hold your breath for a few seconds.
  3. Exhale slowly.

Repeat these exercises once every hour to prevent pneumonia.

6. Pain Killers or Anti-inflammatory Drugs

Pain relievers can reduce inflammation and pain. One of the best is Paracetamol as it has the least side effects. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) such as ibuprofen, aspirin and naproxen are available over the counter. Other NSAIDs for severe cases should be used only when prescribed by a doctor. Using anti-inflammatories may delay the healing process during the first 2 to 3 days.

7. Physical Therapist

Help from a physical therapist can speed up the healing process of the muscles. They can also assist you in your exercises, providing soft tissue massage, joint mobilization, and gentle stretching to improve the range of motion of the spine, mobility, and alignment.

8. Neuromuscular Re-Education

This is a technique used by therapists to restore an individual’s normal movements. With neuromuscular re-education, you can improve your posture and learn the proper sitting, sleeping, and body mechanics to protect the injured parts of the body.

9. Epsom Salt Bath

Epsom salt is effective in alleviating muscular strains. It is composed of magnesium sulfate, which is a natural muscle relaxant. It can also alleviate both pain and swelling.

  1. Add 2 cups of Epsom salt into your warm bath water.
  2. Soak your body in the water for at least thirty minutes.
  3. Repeat this treatment once a day until the strain muscle is recovered completely.

10. Tart Cherry Juice

Tart cherries are packed with antioxidants that can alleviate the pain and swelling of the strained muscle. It also contains high amounts of anti-inflammatory content that can deal with the ache. Simply drink a glass of tart cherry juice once a day to improve your muscle strength and alleviate pain and soreness.
