Patients with tuberculosis do not always have a cough. For mild tuberculosis after treatment with the standard combination of anti-tuberculosis drugs, there can be no symptoms of cough. For simple tuberculous pleurisy causing pleural effusion, etc., at this time there are not many or even no lesions in the lungs, such as occupying tuberculous spheres, and only a small amount of fibrosis and calcification of the pleura and a certain amount of fluid in the lungs, at this time there can be dyspnea, wheezing and shortness of breath, but no symptoms of cough. In addition, in the case of more limited tuberculosis lesions that do not compress the bronchi and pleura, including other lung tissues, the patient will not have coughing symptoms. Therefore, patients with tuberculosis do not always have a cough, but also have other accompanying symptoms.
