Dear Dr's, I am working in overseas around 13years and travel 8 countries. In 2016 I went to Saudi and I took the same GAMCA test, it was cleared. In 2021, again I got an opportunity to work on Saudi and I took the same test but it got failed. The reason behind that is "Right apex and upper tone  infiltration" in my lungs . I have no history of TB in me and in my family. Six months before, I was working in Ethiopia in dust area (river bed). In the centre where I recently took medical test , they suggested me to consult DR and told me to take antibiotic tablets with heavy dose to remove the scars in my lungs. Kindly suggest me what I have to do further.
