Dear Sir, I was affected in TB in the year of 2005 and that time I completed my treatment for the period of six month under doctor's observation. Now its already 11 years pass away, but some time among these years, I am suffer in weight cough which is continue for 3 week & when I go for a test its always negative but I didn't understand why it is happen with me. As per my past experience I feel that ,it is a cough only because other symptoms are not happening with me like fever, wight loss etc. But I am totally confused & in doubt now, that I really come out from TB or not. I don't want to suffer in future again. Please advice me sir .
