I have started symptoms of shortness of breath since over a month. I am 48, never smoked in my life and have lived in pretty non hazardous work environment. It mostly happens typically in morning first half hours or sometimes in evening. It also triggers if I am exposed to a low oxygen environment like driving in a closed car for a while or a crowded unventilated place.
Doctors have tested my blood samples, ecg, 2d echo of heart, stress test, pulmonary function test. All negative. There are no symptoms of allergy nor wheezing etc. Doctors say don't worry, it will vanish. I am quite concerned for not knowing the reason yet and get restless due to feeling of Sob during episodes. Would be great if someone had similar issues and has overcome the same. Appreciate sharing your experiences and advice. THANKS
