Precordial catch syndrome (PCS) is a non-serious condition in which there are sharp stabbing pains in the chest. These typically get worse with inhaling and occur within a small area. Spells of pain usually last less than a few minutes. Typically it begins at rest and other symptoms are absent. Concerns about the condition may result in anxiety. The underlying cause is unclear. Some believe the pain may be from the chest wall or irritation of an intercostal nerve. Risk factors include psychological stress. The pain is not due to the heart. Diagnosis is based on the symptoms. Other conditions that may produce similar symptoms include angina, pericarditis, pleurisy, and chest trauma. Treatment is usually via reassurance, as the pain generally resolves without any specific treatment. Precordial catch syndrome is relatively common, and children between the ages of 6 and 12 are most commonly affected. Males and females are affected equally. It is less common in adults. The condition has been described since at least 1893. Characteristic symptoms include sharp stabbing pains in the chest. These typically get worse with breathing in and occur within a small area. Spells of pain usually last less than a few minutes. Typically it begins at rest and other symptoms are absent. Concerns about the condition may result in anxiety, with sufferers often fearing that the pain is a sign of a more serious condition. Similar anxieties in those who experience the syndrome on a regular basis may manifest as a worry of the syndrome itself happening, with patients feeling scared to take fuller breaths in fear of triggering a spell. The underlying cause is unclear. Some believe the pain may be from the chest wall or irritation of an intercostal nerve. Psychological stress is correlated with precordial catch syndrome. The pain is not due to the heart. Treatment is usually via reassurance, as the pain generally resolves without any specific treatment. Occasionally it goes away after a couple of breaths.
