Experiencing pain in the side of the chest, particularly when breathing, can be a source of significant discomfort and concern. This specific type of pain often points to an issue with the serratus anterior muscle. Understanding the nature of this muscle and the factors that can affect it helps in addressing this common complaint.
Understanding the Serratus Anterior
The serratus anterior is a large muscle located on the side of the chest wall, extending from the upper eight or nine ribs and wrapping around to attach along the inner border of the shoulder blade, known as the scapula. This muscle plays a significant role in the movement and stability of the shoulder blade.
Beyond its role in shoulder movement, the serratus anterior is also considered an accessory muscle of respiration. It assists in drawing the ribs upward and outward during deep inhalation, expanding the chest cavity. Because of this connection to both shoulder mechanics and breathing, issues with the serratus anterior can manifest as pain that intensifies with respiratory efforts.
Common Causes of Pain
Pain in the serratus anterior, especially when exacerbated by breathing, frequently stems from muscle strain or overuse. Repetitive arm movements (e.g., throwing, swimming, or heavy lifting) can place excessive demands on this muscle, leading to microscopic tears and inflammation. New or intense exercise without proper conditioning can also overload the serratus anterior, making it susceptible to injury.
Poor posture is another common contributor to serratus anterior pain. Prolonged slouching or rounded shoulders can cause the muscle to become chronically shortened or stretched, altering its normal biomechanics and leading to fatigue and discomfort. This sustained abnormal positioning can reduce the muscle’s efficiency, making it more prone to strain during everyday activities, including breathing.
Direct trauma to the rib cage or surrounding area (e.g., from a fall, a sports injury, or a car accident) can also injure the serratus anterior muscle. Even without a direct impact, sudden, forceful movements or awkward sleeping positions can sometimes strain the muscle. These injuries can result in localized pain that is sharp or aching and often worsens with movements that engage the muscle, like deep breaths or coughing. Muscle imbalances, where certain muscles are weak while others are overly tight, can also place undue stress on the serratus anterior. For instance, weakness in the core or other shoulder stabilizing muscles might force the serratus anterior to compensate, leading to its overuse and subsequent pain.
Recognizing the Symptoms
Serratus anterior pain typically presents as an aching, sharp, or sometimes stabbing sensation along the side of the rib cage, often underneath the armpit. This discomfort can extend towards the front of the chest or wrap around to the back near the shoulder blade. A hallmark symptom is the intensification of pain with movements that involve the chest and shoulder.
The pain often worsens significantly during deep inhalation, coughing, sneezing, or yawning, due to the muscle’s role in expanding the rib cage during these actions. Simple arm movements, particularly reaching overhead or pushing forward, can also provoke or increase the pain. Individuals might also experience tenderness when the affected area of the muscle is touched.
Other accompanying symptoms can include a feeling of tightness or stiffness in the chest wall or shoulder region. The discomfort might also limit the range of motion in the affected shoulder, making everyday tasks challenging. While the pain is primarily musculoskeletal, its aggravation with breathing can sometimes lead to anxiety or a feeling of breathlessness, even though the lungs themselves are typically unaffected.
Relief and Management Strategies
Managing serratus anterior pain often begins with immediate self-care measures to reduce inflammation and discomfort. Resting the affected area by avoiding activities that aggravate the pain is a primary step, allowing the muscle time to heal. Applying ice packs to the painful region for 15-20 minutes several times a day during the initial 24-48 hours can help reduce swelling and acute pain. After the initial acute phase, switching to heat therapy, such as warm compresses or a heating pad, can help relax the muscle and improve blood flow.
Gentle stretching exercises targeting the chest and shoulder muscles can also provide relief and improve flexibility. Examples include doorway stretches for the chest or gentle arm stretches across the body, performed slowly and without forcing into pain. Over-the-counter pain relievers, such as nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, can help manage pain and reduce inflammation. These medications should be used as directed and for a limited duration.
Improving posture is a crucial long-term strategy for preventing recurrence of serratus anterior pain. Being mindful of how you sit, stand, and perform daily tasks can alleviate chronic strain on the muscle. Incorporating exercises that strengthen core muscles and other shoulder stabilizers can also help correct muscle imbalances, thereby supporting the serratus anterior and reducing its workload.
It is important to seek professional medical attention if the pain is severe, persistent, or worsens despite self-care efforts. Medical consultation is also advised if the pain is accompanied by other concerning symptoms, such as fever, unexplained weight loss, or difficulty breathing that feels unrelated to muscle pain. A healthcare professional, such as a physical therapist or a doctor, can accurately diagnose the cause of the pain and recommend specific interventions like targeted physical therapy exercises, manual therapy, or other treatments to facilitate recovery and prevent future episodes.

Understanding the Serratus Anterior
The serratus anterior is a large muscle located on the side of the chest wall, extending from the upper eight or nine ribs and wrapping around to attach along the inner border of the shoulder blade, known as the scapula. Its name, “serratus,” comes from its saw-like, or serrated, appearance where it attaches to the ribs. This muscle plays a significant role in the movement and stability of the shoulder blade.
Beyond its role in shoulder movement, the serratus anterior is also considered an accessory muscle of respiration. It assists in drawing the ribs upward and outward during deep inhalation, which helps to expand the chest cavity and allow the lungs to fill with air. Because of this connection to both shoulder mechanics and breathing, issues with the serratus anterior can manifest as pain that intensifies with respiratory efforts.
