I was taking Nexium for over two years. I noticed my lower stomach had a pain in it, near the bladder. I stopped taking Nexium and the pain went away. Now my stomach gurgles whenever I eat, it is VERY loud, and I have gas for about four hours. Could this be from taking the Nexium for so long? My doctor said I had an ulcer, from symptoms I told him (sore back, burning sensation in stomach), and put me on the Nexium, but could I now have too little acid in my stomach? Is my body trying to get back to "normal" from using Nexium for over two years, how long does it take for the Nexium to get out of your system after stopping taking it?
