When a patient smokes too much and has vague lung pain, the first step is to quit smoking early to avoid lung irritation caused by harmful substances in the smoke, especially nicotine, which can trigger vague lung pain. Of course, at this time, it is also necessary to go to the hospital to perform a lung CT examination to observe whether there is a corresponding lesion formation in the lungs. For some people who have been smoking for a long time, there is a possibility that lung tumors may form and cause vague lung pain, and for lung cancer patients, targeted treatment is needed. In some cases, patients with lung cancer need to be treated. Sometimes, the intense coughing caused by excessive smoking may lead to vague lung pain, and those with obvious coughing symptoms may be treated with appropriate cough suppression. In addition, long-term heavy smokers may also suffer from chronic bronchitis or pneumonia, which may cause vague lung pain. Patients should also exercise after quitting smoking to strengthen their resistance and reduce the incidence of respiratory infections.
