doctor? I am a 22 year old male who has been suffering with this mysterious health problem for quite a long time now.

Whenever I have my meals or even sometimes randomly in the whole day I feel strange type of nausea like sensation with very frequent belching/burping of air/gas passing from mouth and irritation on the entire body and the skin of my head and even trouble in breathing, I feel so uncomfortable that i stop eating right away.

This problem has been there since i was 17 years old. My doctor always gave me blood pressure controlling pills and never could figure out what exactly was wrong. Now i know he is incompetent and could only tell that i had high blood pressure but not why this problem happened after meals or randomly,
going to any other doctor and spending money on this is something i can only do once i get to know which specialist can figure this problem out, could anybody please tell me what problem might this be and which specialist can cure this health problem?


One more thing i would like to add is that i've been a very addicted fried, spicy and junk food eater ever since i was a kid, could this have caused some problem in my digestive system?
