[|Human|] On vacation this summer in Santa Fe NM USA I experienced difficulty breathing for 3 days. I traveled on to Flagstaff Ariz USA and was fine, next day to the south rim of Grand Canyon, difficulty breathing for 3 days. As soon as I was out of higher elevation I was fine. A few weeks later I flew from Tx to Nv and while in flight experienced the difficulty breathing. I have been checked for any blood clots, none (d-dimer) What could be the problem?
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you are having allergen induced bronchitis. In this type of bronchitis patient feels breathless only for the duration of allergen exposure. Once allergen is removed (go to another place) patient becomes alright. So you may have this. Better to consult pulmonologist and get done PFT (Pulmonary Function Test) to rule out this. No need to worry about embolism as your d dimer is negative.
