question: I had TB before 1o years and completely cured after six month treatment. four years ago i got a visa to Qatar and I had undergone a medical test before leaving my country (India). It was OK . After I reached in Qatar, there was again a medical test and I compelled to return because of TB SCAR. After returned to India, I consulted with two doctors and they said it is only TB scare and nothing to worry. May I know how long tb scar exists in my lungs. Now I got a chance to Abhu Dhabhi. Is there any chance to exists the TB scar in my lungs.
