IM HAVING PAIN IN MY CHEST UNDER MY RIBS AND BACK , HAVE HAD FULL CARDIAC WORK UP ABOUT A MONTH AGO AND EVERYTHING FINE , HAD GASTRIC SLEEVE LAST DECEMBER, PAIN USUALLY STARTS AFTER EATING LASTS ONE TO THREE HOURS. HAPPENING ABOUT THREE OR FOUR TIMES A WEEK NOW. LESS OFTEN WHEN IT BEGAN ABOUT SIX WEEKS AGO.THERE DOES NOT SEEM TO BE ANY PARTICULAR FOOD THAT SETS IT OFF, BUT MORE LIKELY, ANYTHING WITH FAT AND MANY VEGETABLES OR BEANS, ATTEMPTING TO THROW UP RELIEVES PAIN .
