Hi everyone. I was wondering if anybody had any information on causes to chronic stomach pains and stomach aches. My boyfriend has been having stomach problems for a couple of months now and we do not know what it is. He says he feels a pain right below his ribcage in the middle where the stomach would begin. I suspect its acid reflux but tums and maalox do not help. Also he has diarreah and he gets nauseous. The pain is consistent. He has no insurance and no money to see a specialist. He went to the hospital recently and they did a blood test, an ultra-sound, and a rectal exam, and they found nothing. They put him on Nexium and its not helping. What else could it be?
