Thanks for writing to HCM
Whenever there is infection in lungs, during healing process it heals by fibrosis
This is the healed stage finding and it is not infective at all.
Anyone can't deny you on this basis unless your vital capacity
is decreased and your profession demands high capacity. In that case ,you can switch to another profession.
But generally it doesn't affect vital capacity at all unless whole lungs is affected.
Get well soon.
