I just want to ask.. two years ago, i was told by our company doctor that i may have ptb due to the results that they got on out annual physical examination. They said they had seen densities on my right upper lobe. I was instructed to have medication for 6 mos and conduct testing. At first i really cant believe that i may have  ptb. I took medication for only  3 weeks,  because i was on in denial stage and cant accept the fact that i may really have ptb, . And now we are about to have our Annual examination again and i'm so afraid. Can it be cured within 3 weeks of medication?
