I have spot on my lungs- unfit to work?

Lung spot: Medical journey, fit or unfit to work? Hi guys, Just want to share with you my recent experience about my medical process, the things I have undergone and the result. I am new here in Qatar by the way. I was here for about 2 months already and was waiting for my company to call me for the position that I applied for. When they finally arranged my papers and all for the processing of my visa and Qatar id, I had to undergo medical. Well, all companies require that as part of the process before the government issues your work id. I was sent to the Medical commission for Blood and Xray . After about 3 days, I got an email from the hospital and from the company PRO advising me to come back for a second xray because they have to have a clear vision of my left lung part as they are seeing something blurry there and have to make sure what it is. I immediately returned for the second xray and it is done. 24 hours later they emailed me again saying that I have to have an appointment with another doctor to perform some more tests. The email also stated when is the date and to which doctor do I need to report to and what room. I was then surprised that I had to perform Mantoux test. (The Mantoux test or Mendel–Mantoux test is a tool for screening for tuberculosis and for tuberculosis diagnosis. It is one of the major tuberculin skin tests used around the world, largely replacing multiple-puncture tests such as the tine test – Wikipedia) Actual picture of the Tuberculin test is on the display pic of this article. I was then confirmed to have/had TB. Results were latent TB. I had pneumonia 11 years ago and I thought that was just it because I never had any complications after but to my surprise, I was left with a scar on my left lung. They referred me to communicable disease center for further testing and took medications for about 3 months. 3 tablets a day for 3 freaking months! Following up every month on the progress and to check if I have chemical reaction to the medicine they gave me. After 3 months, when I returned to CDC, they took sputum and blood test just to make sure that everything is fine. The results went fine and I got my Qatar id afterwards. This whole journey was a bit of a roller coaster ride. Went here and there, took too many blood samples and tests but the results turned out fine so I am thankful for that. It6’s just so sad that just because of a scar that’s been long cured affected me the most. It is stupid. Least thing to say but at least I was able to be treated properly and took the right medications to stay healthy. Now I am happy with my current job and will stay and continue taking care of my health because health is wealth.
