I had very mild asthma when I was much younger. I used to take asthalin inhaler. Now, few days ago, I had severe acidity due to which I am having burps just after having anything. Also, feeling like something is stuck in my throat. Also, feeling shortness of breath and having the urge to yawn or take deep breaths. How many days will it take to cure this? And what should be done? Also, I was having constipation few days back, but that got resolved. But I am worried about the shortness of breath.
