Abdomen problem. The problem may be?

I am having following symptoms: Loud noise burping, abdominal distension almost whole day, redness and itching below ribs on both side except centre. I had diarrhea like symptoms about 1 week ago with all these and a homoeopathic doctor diagnosed it as gastritis with dyspepsia. As soon as i eat something i pass a lot of gas in form of burping but abdomen remains distended and as soon as around 3 hrs complete i feel extremely hungry and gas fills up in whole body even head and gets relieved much after eating something. I am also noticing palm and feet warmness since a few weeks and all these abdomen related problems i have since about 1 month. The gas gets much relieved after having dsr or anything as an antacid. What should be my next step and what the problem may be?
