Hi! i have a scar in my chest cause by stab wound and the tube that put inside my lungs to draw out the blood way back 2005, and since then everytime I get my xray result a scar always show in my left lung where the stab and operation was performed. I did my medical exam 6months ago and explained to the attending physician my case and I am negative to PPD test but today they want me back again at the Xray Section. I work for a cafeteria here in Qatar and I am scared to death that I might get deported for having a scar on my lung that would never go away anymore.
