Tuberculosis of the lung presents in many forms, as there are also various types of pulmonary tuberculosis, each exhibiting different symptoms. However, the most common symptoms primarily include coughing and expectoration, which are the most typical manifestations of pulmonary tuberculosis. The cough in pulmonary tuberculosis is generally mild, either dry or producing only a small amount of phlegm. If the tuberculosis is accompanied by cavities, the amount of phlegm may be larger. If there is a bacterial infection in addition to the tuberculosis, the phlegm may become purulent. Some patients with pulmonary tuberculosis may also experience hemoptysis, which can vary in amount from light to severe. A small number of patients may suffer from chest pain and difficulty breathing. Additionally, there are systemic symptoms associated with pulmonary tuberculosis, such as fever (both low and high fever may occur), night sweats, and fatigue, among others.
