Hi SianIt is true that sometimes even gas could lead to back pain -- if the pain travels up and down, then that's most probably gas -- I've had this happen to me many times. But gas pain at the back can't be too severe -- if it's really bad, then may worth checking with the dr. And, back pain is *not* a typical symptom of GERD -- my GERD, if uncontrolled, is really bad and I can get severe chest pain and uncontrollable coughing fits and painful throat which makes swallowing anything painful, BUT I don't have any back pain related directly to my GERD (just goes to show how atypical it is for GERD sufferers to have back pain). If it is a pain that has a pattern and always occur at roughly the same location and same time, then that's worth checking up -- usually if pain occurs between the shoulder blades and to the right lower edge of the shoulder blade which occurs or gets aggrevated after eating/drinking and lasts from 30 min. to a few hours, then one needs to have the gallbladder checked out; if pain occurs anywhere upper back esp. after eating greasy food or eating a big meal and lasts from hours to days/weeks, then one needs to have the pancreas checked. There's quite a few organs in that small area and any of these can give similar symptoms -- so it may worth it to get to the bottom of it, to just stay on the safe side, you know...
