[/INST] Hello As you mentioned that you took complete anti-tubercular treatment stipulated for 6 months.X-ray chest is clear. Your fear is correct, if you are already a patient of tuberculosis, please take care. Whenever develop cough, fever, loss of weight, anorexia, expectoration, at once report the physician and tell him that you are an old treated case for tuberculosis. As I have noted in my so many cases that whenever they develop cough report immediately. Don't consult any quacks, rather consult a physician (qualified) and take treatment.Don't take any immunity lowering agents like smoking, alcohol etc. No need to take any tension, deal as mentioned above and tuberculosis will never recur. </s>
