<s>[INST] I work in a building that is seventeen years old five days ago a major waterline broke and flooded the whole north side of the building. The ceiling came down on three floors. So I had to walk through dripping water and flooded floors. About three days ago my chest feels heavy and i have shortness of breath when I talk. My job requires a lot of walking that does not bother me. Is it possible that I might have breathed in mold and if so what should I do. [/INST] Hi, I understand your concern. I think you might be having a lung infection. I advise consulting with your physician and run chest X-ray to determine the right diagnosis. For the moment, I can only advise to take antihistamines (e.g. loratadine) until you see your doctor. However, I still think you should go to clinic immediately. If you cannot manage, then, go to ER to check your problems with difficulty in breathing. Wish fast recovery. </s>
