<unk>  (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.<unk>  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.
