Cough and sputum: easily recurring and not improving for a longer period of time. Coughing white mucus sputum mostly, and pus sputum may appear when accompanied by other infections. In case of combined bronchial tuberculosis, the cough is irritating. When there is cavity formation, the sputum volume increases, and if combined with other bacterial infections, the sputum may be purulent. 5.

If the pain site is not fixed, wandering, pain is not related to breathing, coughing, most of the pain caused by nerve reflex. 7, chest tightness and shortness of breath: the lung tissue is widely and severely damaged, or there is extensive pleural adhesion, shortness of breath can occur, especially after physical activity aggravated. 8, Other: Patients may have loss of appetite, gradual loss of body weight, lesbians may have irregular menstruation or even amenorrhea, children may have personality changes, irritability and irritability.
