Why Does My Side Hurt When I Cough? Causes and Relief

Pain in the side when coughing is a common experience, varying from a mild ache to sharp discomfort. Understanding its potential causes can help determine its origin and when to seek medical attention.

Common Musculoskeletal Explanations

Coughing involves a forceful contraction of various muscles in the torso, and this exertion can sometimes lead to muscle strain. The intercostal muscles, located between the ribs, are frequently affected as they play a role in breathing and the mechanics of a cough. These can be overstretched or torn during strong or prolonged coughing. This strain results in localized pain that often worsens with movement, deep breaths, or continued coughing.

Another frequent cause of side pain with coughing is costochondritis, which involves inflammation of the cartilage that connects the ribs to the breastbone. This condition can cause sharp, stabbing chest pain that radiates to the side, often mimicking heart-related issues. Coughing exacerbates costochondritis pain by moving the inflamed cartilage. Applying pressure to the affected area, such as between the ribs, might also provoke tenderness.

Beyond muscle and cartilage inflammation, issues with the ribs themselves can contribute to pain when coughing. Minor rib bruising can occur from direct impact or repetitive forceful coughing. In some instances, persistent and severe coughing can place enough stress on the ribs to cause a stress fracture, particularly in individuals with weakened bones. Less common, these rib issues cause sharp pain that intensifies with coughing.

Respiratory System Involvement

Inflammation of the pleura, the thin layers of tissue surrounding the lungs and lining the inner chest wall, is known as pleurisy. These layers normally glide smoothly past each other during breathing, but when inflamed, they rub together, causing sharp pain. This pain is often exacerbated by deep breaths, sneezing, or coughing, and it typically feels like a stabbing sensation in the side or chest. Pleurisy can arise from infections or other underlying conditions affecting the lungs.

Infections such as bronchitis or pneumonia can also lead to significant pain when coughing. Bronchitis involves inflammation of the bronchial tubes, which are the main airways of the lungs, while pneumonia is an infection that inflames the air sacs in one or both lungs. Both conditions cause irritation and inflammation within the respiratory system, leading to persistent coughing. Sustained, forceful coughing can strain surrounding muscles and tissues.

For individuals with pre-existing respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD), an exacerbation can trigger severe coughing fits. These intense coughing episodes place considerable stress on the respiratory muscles and the chest wall. Prolonged, vigorous contractions during these attacks can lead to muscle fatigue, soreness, and strain. Managing the underlying respiratory condition is important to reduce the frequency and intensity of these painful coughing episodes.

When to Seek Medical Care

While many instances of side pain from coughing are not serious, certain signs indicate the need for professional medical attention. Individuals should seek evaluation if the pain is severe, rapidly worsening, or does not improve after a few days of self-care. Persistent or escalating pain could signal a more significant underlying issue that requires diagnosis and treatment.

Additional symptoms accompanying the pain should also prompt a medical visit. The presence of fever, chills, or shortness of breath alongside the pain could suggest an infection like pneumonia. Coughing up blood or discolored mucus (green, yellow, or rust-colored) warrants immediate medical assessment. If pain developed after a fall or direct chest/side injury, seek medical attention to rule out fractures or internal damage.

Temporary Relief Measures

Resting the affected area can help alleviate side pain caused by coughing. Avoiding activities that worsen the discomfort, such as strenuous exercise or heavy lifting, allows strained muscles and inflamed tissues to recover. Adequate rest reduces irritation and promotes healing.

Over-the-counter pain relievers can provide temporary relief from pain and inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help reduce both pain and swelling. Acetaminophen can also be used for pain relief, though it does not reduce inflammation. Always follow the dosage instructions on the product label to ensure safe and effective use.

Applying a warm compress or a heating pad to the painful side can help relax tense muscles and improve blood flow to the area. Heat therapy can soothe discomfort caused by muscle strain or general soreness. Using a warm compress for 15-20 minutes several times a day can offer noticeable comfort.

In cases where the cough itself is particularly severe and non-productive, a cough suppressant might be considered to reduce the frequency and intensity of coughing fits. However, it is advisable to consult with a pharmacist or doctor before using cough suppressants, especially if there is underlying respiratory illness or if the cough is productive (meaning it brings up mucus). Supporting the painful side by holding a pillow firmly against it when coughing can also lessen the strain on muscles and ribs, providing immediate, localized relief.
