There are many causes of chest pain when breathing in the elderly, the more common being pleurisy, and the symptoms left over from pleurisy. If there is a recent history of upper respiratory tract infections, viruses, bacteria, tuberculosis bacilli and other invasions of the lungs can lead to acute pneumonia and pleurisy, and the main symptoms will be manifested as chest pain when breathing, chest tightness, and even dyspnea. Skin infections of the chest wall, herpes zoster, costochondritis can also cause chest pain. Herpes zoster may not show a rash in the early stages, and often only shows simple chest pain, once the rash appears, the diagnosis of herpes zoster can be confirmed. In addition, the elderly also need to be alert to the possibility of angina pectoris, myocardial infarction and pneumothorax at the same time.
