I'm really concerned about this issue I've been having. A couple of years ago, I was in a room with some agarbati burning, and after about an hour, I started having chest pain and an itchy nose, followed by shortness of breath. It took me a few days to recover from that, and ever since, I've noticed that I get the same symptoms if I'm around any smoke, like from agarbati or mosquito repellents. I saw a pulmonologist back then, and he gave me some meds that seemed to help over time, but he never said it was asthma. I'm wondering now if I've developed asthma or if these are just triggers since I feel fine otherwise. I'm a bit anxious because I'm about to take a flight soon, and I'm not sure how to handle it if something similar happens at such a high altitude. Could you give me any advice or insights on what I might be dealing with and how to prepare for the flight?
