Patients who experience chest pain with slight activity may be suffering from pleurisy. When pleurisy is caused by bacterial infection, chest pain, coughing, chest tightness and shortness of breath can occur. Patients often experience increased chest pain with deep breathing and violent coughing, and they may also experience fever, chills, weakness of the limbs and loss of appetite. In addition, the appearance of chest pain may also be caused by trauma, such as patients with strained chest muscles caused by strenuous activities, they may have symptoms of chest pain. Patients who suffer from rib fractures or pneumothorax due to trauma may also experience chest pain, which may be aggravated when they move around. Patients suffering from heart diseases may also experience chest pain, such as those suffering from coronary heart disease, viral myocarditis, and cardiac neurosis.
