Age 54 m my acidity or gastritis is worsening. my whole body aches and i feel sharp pain in my heart and liver area and also on the lower abdomen. it comes & soon as i release gas through belching or a burp the pain settles down. tests to do ? thx?

Whole body aches are unusual with digestive type symptoms. My sense is that gas buildup is the issue. Either you're producing excess gas or normal gas but it's not moving down the intestinal tract. You may have lactose or gluten intolerance. Try eliminating one &then the other. Take simethicone after meals& avoid gassy foods&beverages. Consult a gastroenterologist if not improved.
