question: Hi doctor, I am suffering from shortness of breath after vaping e-cigarette. I consulted doctors and they said my lungs are fine. I read on the internet that a lot of people suffering with the same. When I reduce my e-cigarette I feel better. Also, I had FESS surgery and SMR before two weeks. My current medication is nasal spray Propolis. Is my problem related to acid reflux? Please explain me.
