Dear friend, welcome to HCM.
in this case there is apossibility of aspiration of the food into the airway, or lungs causing intense inflammation
or some food getting stuck in the deeper airway.
a food like foreign body in the airways can give no shadow on an Xray and cause inflammation as in your case. it can get serious if untreated. would advise you to see your physician and get evaluated for these possibilities.
a Xray chest and an endoscopy
may be needed.
let him be fasting till you reach your doc/ ER room.
do not play around with the problem at home.
I hope to have answered your query satisfactorily.
Take care and please keep me informed of your progress.
Good Luck !
