食了2個月肺結核藥陰影還在??

The calcified tubercle usually life-longed. Therefore, even though
you take a chest x-ray after 1 year, doctor still know you have past
PTB history because of this calcified tubercle. However, calcified
tubercle may disappear in very little group of patients.
After start the antiTB therapy for 2 week, there is already
non-infectious.
Doctors must let you know if the therapy is ineffective. No worries.
