Cough, chest tightness and sputum are usually seen in infectious respiratory diseases, including bronchitis, bronchiectasis, lung infections, and tuberculosis cannot be excluded. Once cough, chest tightness and sputum occur and the diagnosis of lung infection is confirmed by chest X-ray, antibiotic treatment including penicillin, cephalosporin I and II antibiotics, and also fluoroquinolone antibiotic ofloxacin need to be given as soon as possible, all of which can effectively control the lung infection and relieve the respiratory symptoms as soon as possible. Pulmonary infection with phlegm also needs to be given herbal treatment. Chinese herbal medicine can be given to clear heat, dissolve phlegm and stop cough, promote lung dispersal and stop cough, which is more ideal with antibiotic treatment. Once clinical chest tightness and sputum occur, chest X-ray needs to be taken as early as possible to exclude tuberculosis and lung cancer. If it is a common infectious disease of the lung, antibiotics and Chinese herbal medicine treatment should be given as early as possible, which is very effective.
