Thanks for your question on Health Care Magic.
I can understand your concern.
Upper lobe lung lesions can be due to
tuberculosis or
pneumonia.
Treatment of tuberculosis is for atleast 6 months.
And treatment for pneumonia is for 10-14 days.
So it is better to get done repeat chest
x ray after 14 days of antibiotic treatment.
If you are having simple pneumonia than it will be cleared in new x ray.
But if it is tuberculosis then it will not clear.
This is the reason why pulmonologist called you after 14 days with fresh chest x ray.
So get done repeat chest x ray after 14 days.
You may also need bronchoscopic evaluation to rule out tuberculosis.
Hope I have solved your query.
Wish you good health. Thanks.
