Chronic Flatulence, Need help plz

Dear all,

I am a 26 year old guy from India who is suffering from chronic flatulence for the past 15 years.

No particular other problems like constipation diarrhea.I have tried many doctors and still no cure. I am irritated with this cause its not possible to go to work like this and can't do any social activity for the fear of passing gas. This problem has wrecked a havoc in my life. I have spent almost 600$ from my savings after this to absolutely no benefit. Can anyone help me out with this?
Almost everything I eat gives me gas and it has nothing to do with my diet.

Thanks in advance
