been diagnosed with koch's disease last 2002. had taken medicines for 6 months. an xray was made again & the densities seen in the upper right lobe of my lungs was still there. after a year taken again 6months medicines & not yet disappeared. the doctor said it was already a scar. this 2013, just last week we had an annual physical exam & i told the radiologist they will seen something in my upper lobe which is already a scar & she told me to bring all my past xray films for comaprison. now i received the result & they were suggesting for me to do the apicolordotic xray. do i have to do it over & over again? i've done this many times & so tired explaining to them that this is already a scar. & i rigolously consult doctor & had a sputum test for 3 consecutive days & the result is always negative meaning there is no bacteria found in my sputum. what can u say with this?
