The calcified stage of TB lesions usually does not cause lung discomfort. The calcified phase of tuberculosis foci is diagnosed by imaging, with X-ray showing increased density of lymph nodes in the lungs and grossness around them. Calcification of tuberculosis foci suggests that the tuberculosis is already in the recovery phase, and that it is a kind of old lesion, which is due to calcified foci caused by scars in the lungs. Clinical chest X-ray or lung CT, often found in the lungs of the calcified foci, suggesting that may have been infected with tuberculosis, but due to the body’s resistance is relatively strong, but only occult infection and the formation of calcified foci, so the patient often do not have obvious coughing and coughing sputum and other symptoms. Clinically, calcified foci in the lungs usually do not lead to symptoms of lung discomfort or coughing up sputum, if there is discomfort in the lungs, it is recommended to consult the respiratory medicine department or the infection department of a regular hospital for further diagnosis and treatment.
