I get shortness of breath while talking in presentation or during a long discussion in the office meetings. I sweat as well and start feeling giddy as well for sometime once I stop the discussion and calm down I come to normal again. I have done PFT , CHEST PA XRAY AND ECG as well as 2d echo cardio scan but luckily all the reports are normal. My physician said it may be allergic asthma due to weather changes, change in places while traveling and well as trigger of anxiety. I need proper advice.
