Lumbar pain for 3 days, lung CT said there was a nodule in the lower left.

Disease analysis: Hello, according to your description, what ct found is an old pulmonary nodule, which is a calcification point formed by incomplete healing of tissues caused by previous diseases; Generally caused by pneumonia, tuberculosis, lung abscess and other lung diseases. It is a "scar" formed in the process of lung tissue repair when the disease is treated or cured.

Guidance: Hello, your illness is probably old tuberculosis. Pneumonia and lung abscess are difficult to heal themselves without effective treatment. However, some patients have no symptoms after being infected with tuberculosis, and they calcify themselves without treatment. Only when they are found in future visits will they know. I suggest you go to the local CDC for diagnosis. According to the modern tuberculosis control strategy, even old tuberculosis should be treated with anti-tuberculosis drugs for six months, so as to achieve complete sterilization and avoid the possibility of recurrence.
