Dry pleurisy is an early manifestation of tuberculous pleurisy, when the pleura is congested, edematous, and has a small amount of fibrinaceous exudate on the surface. Clinically, the onset of the disease is rapid, feverish, and accompanied by mild chest pain that worsens with coughing or breathing. Dry pleurisy is characterized by the fact that it can occur in any part of the pleural cavity. Its symptoms vary in severity; some patients have few or no symptoms and it can resolve spontaneously. Some have a more acute onset with chills and mild or moderate low-grade fever, but the main symptom is limited pinprick chest pain. Chest pain is caused by the friction between the wall layer and the dirty layer of pleura close to each other, so the chest pain is mostly located in the anterior axillary line or the lower part of the posterior axillary line where the amplitude of the respiratory movement of the thorax is the greatest, and the chest pain is more serious when breathing deeply and coughing. If the lesion occurs in the lung apical pleura, dry pleurisy can be characterized by chest pain radiating along the brachial plexus, so that the hand pain and perceptual disorders, such as in the center of the diaphragm, the pain can be radiated to the same side of the shoulder; the lesion in the peripheral part of the diaphragm, the pain can be radiated to the upper abdomen and the fossa of the heart. As patients with chest pain do not dare to inhale deeply, so the respiration is rapid and shallow, when the vagus nerve is stimulated, it can cause intractable cough. Physical examination reveals restricted respiratory motion, localized pressure pain, decreased breath sounds, and pleural friction sounds can be touched or heard, which can be heard regardless of expiration or inhalation and is unchanged after coughing. At this time, pleural friction is an important sign. Generally speaking, dry pleurisy is the early stage of tuberculous pleurisy, and pleural effusion will soon appear. Thickened pleural adhesions are a manifestation of old pleurisy, which, unlike dry pleurisy, requires surgery in severe cases.
