You have not given enough information. When did you complete your treatment, do you still have symptoms like fever, malaise, cough with sputum
, poor appetite
, weight loss
etc. Some times TB lesions heal with fibrosis and may leave scar and may be difficult to differentiate from fresh lesion. If you are healthy and do not have symptoms as i`ve mentioned above, it may be healed tb. But if you have such symptoms, the disease may still be active and you need to get investigated and treated properly. Please consult a pulmonologist
who can guide you correctly.
