I feel a wheezing sound on upper chest or lower throat immediately after completing my meal, wheezing is more if the food is spicy, otherwise less, postnasal drip also runs upto 5 minutes of eating?. Once I also used to lead a normal life, but suddenly this happened, Is this food allergy or something other, bcoz my chest x ray is clear, antibiotics didn't work on it. Can this be cured off from root. Is this allergy bcoz I only have problem after eating food. Otherwise I Don't cough and if I try to cough deliberately, no phlegm spit out This is also not GERD. I have confirmed it.
