Chest & Breathing Problems

My elder brother is in army job, he just completed all the 15 quarantine days in an isolation ward in suspect to COVID 19. He had cough, fever and weakness for 1.5 week but after several tests he founded out to be COVID negative. Due to strictly rush duty schedule, he has to start his daily job even after he is not fully recovered from the weakness and has a weird breathing issue of getting a ugly smell of something like old phlegm while inhaling and exhaling and a feels like burden on lungs. Is it somewhere related to not getting enough rest time or something more serious is hidden? Please tell sir/madam ,

A couple of years back I used to smoke heavily and noticed difficulty in breathing after which I completely quit smoking. But, whenever I felt urge I would consume one cigarette and experience the same issue. Hence, for last one year I don't touch a single piece. But, the problem resurrects. Nowadays, I experience shortness of breath very frequently, like feel for a long deep breath. Upon hard work the problem increases, what should I do?
