welcome to hcm ..mam upper right lobe infiltrates means two possibilities
1 ..it is fresh tb as some person even after complete and successful cure again develop tb ...not all but some
2 ..it may be healed past tb as the xray shadows persist for upto 6 months to 1 year after successful cure of tb
now what symptoms you are giving it may or may not be tb ..
For confirmation of tb ..please undergo sputum test of 2 samples under microscope for tb bacteria ..it is done free of cost in govt hospitals in india
and next is raised
ESR and raised lymphocytes in
TLC DLC
besides this chest and tb specialist are well qualified to distinguish between healed and fresh tb on chest xray
last option is chest
CT scan and CB NAAT test also available at govt hospital
i advise tlc ..dlc ...esr ...sputum test and chest xray reading by chest and tb doctor along with your symptoms will clear the doubt
till the tb doubt is clear take the medicines as you are taking...in post tb cases if symptoms persist and tb tests are normal i also advise ct chest
i hope i have solved your query about how i proceede in our indian setting as you appear to be indian ..but what i told above applies worldwide
if you have any further query you can contact us
