I Have Small Amounts Of Food Stuck Above My Epiglottis.

I have small amounts of food stuck above my epiglottis. This was confirmed with a barium swallow fluoroscope. The most that was offered at the time was swallowing and tongue exercises that don't seem to have much efficacy (as defined by the literature and also by my own attempt at doing them for 3 weeks.) This includes swallowing with the tongue between the teeth and effortfull swallowing.Anything else i can do to dislodge this food when it occurs? Any epiglottis exercises?
