Hello I have gone through your question and understand your concern. Unfortunately scarring caused by the healing of lungs due to pulmonary tuberculosis is almost unavoidable. If your are concerned about not being able to get a job due the scar on x-ray then the issue can be taken care of and it is nothing to worry about. All you need is to consult a pulmonologist, get few diagnostic tests to show that currently patient is healthy with no active tuberculosis. And a written note from the pulmonologist about your previous illness and the course of treatment followed and the scar seen on x- ray is a fibrotic scar from healing. Hope your concern is answered. Thank you.
