Hello docotor, I am having severe abdominal pain for the last 2 weeks. It is kind of vague contracting type of pain, lasts only a few seconds then comes again, with lot of belching. I consulted a gastroenterologist and he did an endoscopy, nothing was found, and the pain is still there. I am taking, rabeprazole sodium and Cilakar. I am having high blood pressures. I just want to know what it could be?. Is it due to BP or something else?.
