[|Human|] Hello sir I would like to ask you about my husband.he is 30 years old..he had tb two times and now he recovered after taking medicines but a scar has remained in his lungs..will that scar remain forever? Will that scar have effect on his life span? can he do exercise?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about this scar lesions in lungs. All lung infections including tuberculosis heal after treatment. They heal mostly by following three mechanism. 1. Fibrosis (most common) 2. Calcification. 3. Rarely Complete resolution. So this fibrosis look like scar lesions on chest x-ray. They are inactive, noninfectious lesions. So no treatment is required for them. They will remain as it is throughout the life. No need to worry as they are harmless. And these scar have no effect on his life span. Yes, he can definitely down exercise. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
