hi :) i found this forum helpful, thanks for this :) anyways, i was just curious. i just wanna ask, i undergo 6months medication on PTB, negative sputums on it. after i finished medicine intakes (jan. 2014) after a month, i had my chest xray for pulmo clearance (i had my xray feb 2014) on apico lordotic view says there are infiltrates on left lobe compatible with PTB with undetermined activity i was still wondering, i response well on the medications, i gained weight, i take vitamins, full time rest, negative sputums, why is that? as a nurse friend explains its already a scar, does it mean the scar is not yet healed? or i have to undergo medication again? i know i should avoid stress, but when i am thinking of this i feel about depressed coz i really wanna be back to work. hope it could answer some of my curiosity i was worried because i feel im not okay still. thankyou
