thank you for your query.
what you are describing as is called Pulmonary fibrosis
.it is a complication of long standing infection such a TB.unfortunately it has no cure. because once lung scarring has developed, it is permanent and irreversible. The only real cure is a lung transplant
you can just keep getting a check up done every 6 months to check on the scarring if you have any additional symptoms such as shortness of breath
wishing you good health
