You did not mention whether you had tubercular pleural effusion
or not. From history,it appeared to me as you had tubecular pleural effusion because you told that effusion got cleared with treatment. Tubercular pleural effusion may leave behind residual pleural thickening. If you had concomitant pulmonary tuberculosis
, it may also lead to residual pulmonary fibrosis
. Chest X-ray of pleural thickening and pulmonary fibrosis will not be clear. But that does not mean you have active pulmonary tuberculosis. If a person do not have acid fast bacilli in sputum or mycobacteria
in culture, then the person is noninfectious to others. As fer my knowledge is concerned,there should not be any reason to not give you visa. Regarding your fitness, if you have residual pulmonary fibrosis or pleural thickening, then you may have restrictive lung disease
depending upon it's extent. But as you are asymptomatic at present, I think even if you had pleural thickening or fibrosis, that is mild and will not affect your fitness in day to day practise. But as I had not seen your X-ray, it's difficult to give a definite opinion. Hope,I satisfied your queries.
