Hi @tdrell I work in a call center. I only had CT scan, xray, afb culture, sputum culture and broncoschopy. I dont smoke and dont have asthma. When I was diagnosed with bronchaectasis in 1997 my pulmo never explained to me he just based his diagnosis on xray and afb culture and I took anti TB drug for almost 3 years. I was never diagnosed TB but he said the treamemt is same as TB. After 1 month of taking meds I stopped coughing and seldom had cough for 10 years I though everything was OK I was cured. It started back when I started to work in a call center I suspect that since I work on night shift and having trouble sleeping on daytime my immune system begun to drop thats why I got an NTM. Im planning to find a day shift job to see if this will help. THANKS!
