Chest pain during the recovery period of tuberculous pleurisy may be caused by pleural adhesion, poor control of inflammation and pleural effusion. 1. Pleural adhesion: when suffering from tuberculous pleurisy, the pleura may ooze out the effusion containing a lot of cellulose and cellular components, resulting in pleural adhesion. During the recovery period, with the decrease of pleural effusion, the two layers of pleura may be more seriously adhered, and obvious chest pain may appear. 2. Poor control of inflammation: If there is poor control of inflammation during the recovery of tuberculous pleurisy, it may lead to chest pain in the pleura under the stimulation of inflammatory factors. 3. Pleural effusion: if pleural effusion occurs during the recovery period of tuberculous pleurisy, it may also cause symptoms of chest pain. It is recommended that patients with tuberculous pleurisy in the recovery period should go to the regular hospital in time to clarify the cause of the chest pain, and actively treat it, so as to avoid delaying the condition.
