For 10 years I have had periodic pain in the rt. quadrant of my stomach and taken all the tests: ultra sound, gall bladder test, endoscopy, X-ray with barium, etc. All were negative. Only an MRI is left this week. I've been on acid reducers, protonix,nexium and, more recently, prilosec (once a day, and sometimes at night), and Tums/Maalox during the day when needed. Acid stomachs run in my family: father (perforated ulcer), brother (surgery). I'm 73, and in excellent health (work out, etc). If I watch my diet, the pain is intermittant and kept to a minimum. I I take a vitamin supplement once a day. How safe is it to continue taking all these anti-acids? Is this condition common? Would a nutritionist or other professional/consultant be helpful? Thank you.
