I,ve had this horrible stomach condition for over two months now. my symptoms include, bubbling,nauseous,acidity,pain,gaseous, pain going right through my back. I can,t even roll over in bed, it wakes me up. I,ve had an ultrasound, and an upper GI. Nothing was found. Could it still be an ulcer? I also have graves disease and this isn,t helping.Can you help?
