What is the cause and the solution of what seems to be a traveling pocket of gas up and down my back , chest , rib cage with sometimes a griping pain ?

Multiple causes: Increased gas formation may be due to drinking too much carbonated beverages, eating too quickly, not chewing food well before swallowing, high fiber diets...A gas bubble that gets caught (often in the right or left upper quadrant of abdomen) can cause pain in various parts of chest and abdomen. Try correcting above listed problems; then try gas-x, or an otc product with simethocone three daily.
