I've been dealing with this choking sensation for almost a year now, and it really feels like I'm short of breath. I end up coughing a lot, trying to make it better, and it kind of feels like I'm going to vomit, but nothing ever comes outno vomiting, no sputum. I haven't had any fever either. I got a chest X-ray done a couple of days ago and everything seemed normal, and about five months ago, I had an HD Chest Scan, 2D Echo, and another X-rayall normal too. I'm taking Montek LC half a tablet at night and using an inhaler, but nothing's helping. What could this be?

take syrup ascoril twice a day for 5 days
