Welcome to HCM
After going through your history, you have suffered PTB which was successfully treated with complete course for more than 6 months.
Even after healing of PTB these scar in apex of lungs persist, there is no treatment required.
These X ray
can be compared and other parameters like clinical examination and other tests like CBC ESR
and sputum test are taken in consideration before treating such case.
If you do not have any symptoms like cough
, loss of appetite and weight loss
then you do not need to worry.
Reactivation of PTB is possible specially if there is any condition which reduces immunity in your case it seems unlikely.
If doubt take opinion of local Physician,
