Hi Doctors. Hope You Can Help Me. Went For Over

Hi Doctors. Hope you can help me. Went for over all medical last Aug 5 2015. Waited until aug 10 for the lab report. Result, everything was okay except my xray. They saw PTB right upper lobe, but they were not sure so they repeated my x-ray on that day (10th of aug monday) on my right upper. Then have go back again next day 11th Tuesday(aug 11, 2015). Then they confirm that i have PTB right upper lobe which surprised me, never had this before. So they give a antibacterial med (Clarithrocid 500g) for 7days and told me to go back after 10 days. But since the 10th day is holiday, i went back the next monday (24th of aug 15). They reapeat my x-ray again (spot & CPA or PA? Correct me if im wrong). The i have to wait again until next day for the result. Went back again next day Tuesday, but the doctor said, the result has not change. Why is that? Are they give the correct medicine? And then, they wanted to re-read it again, let me walk away without giving me any medicine for treatment, and wanted me to go back again this coming Thursday, which means tomorrow. And if still the same, they are going to give me an unfit to work. What should i do? Its geopatize my opportunity, my job is waiting for me. My employer told me if i can take the midication there. I am going to work abroad. Thought, PTB is highly and can easily cured? Why they are not telling me any options? I feel like they are just playing with me. Any suggestions? just need options or advice.
