Talk to Gastroenterologist on IBS

hi there, i m suffering from stomach problem, whatever i eat, that straightaway creates gas insde my stomach, often the gas gets struck inside because my colon gets dry. recently i consulted a doctor, he gave me the medicines and ask me to get couple of tests done(Urine+Stool tests) what all were fine with a 5.4 HP level. afte4 eating medicine for 11 days, i felt a bit relieved and went to the doctor for follow up, he told me that i get swelling in my intestines, so i should keep up with the medicines and eat Barley Dalya(morning) and ispaghol with milk(night time) i m doing so, but still i feel i get too much gases all the times, and i feel embarrassing to be any where. could anyone plz suggest me something. thanks
