[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. You are mostly having old healed tb lesion. You had tuberculosis in the past. And TB lesions after treatment heal by either fibrosis or calcification. Fibrosis or calcification will be seen as whitish patch throughout the life. No treatment is required for these lesions as they are inactive scarred lesions. You recurrent cold, cough etc. are mostly due to bronchitis (inflammation of airways). It is common after lung infection like tuberculosis. So get done PFT (pulmonary function test) for the diagnosis of bronchitis. PFT will also tell you about severity of the disease and treatment is based on severity only. You may need inhaled bronchodilator and inhaled corticosteroids. No treatment is needed for patch. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
