The doctor said i have reticular infiltrate in my upper right lobe of my lungs, i'm just curios cause i have no vice and not expose to any hazardous chemical or even dusty places as far as i know, but then the doctor said i have PTB vs pulmonary even if no symtoms or any indication that i have that desease cause if you look at my body i'm very much healthy and no indication of the said desease, in short after i undergone a medication intaking of clarithromycin that prescribe to me then all of a sudden in my x ray doctor said i have pulmonary scar which is not visible during my first xray, is it possible because of the drug i intake that cause me scar in my lungs.
