I have been diagnosed with Asthma and I use an inhaler daily, but lately I have been experiencing uncontrollable exhaling. At this time, my sinuses are not stuffed up or clogged in any way, but I have continuous mucus running down the back of my throat. It collects in my lung and affects my breathing and have to cough it up. The exhaling issue happens when I feel a little itch/tickle in my throat which starts a low volumn cough 8 to 10 in a row rapidly in which I have no control. It empties ever bit of air in my lungs and I have to force myself to gasp for air.
