have you tried the holistic aproach. go see a nutritionist if you can because one thing i have learned is that only one out of hundreds makes to much stomach acid. the heartburn or what they call "gerd" is usually from to little acid. I am extremly ill and down to 100 pounds and i cannot eat. ive been drinking smoothies with protien and vitamin powder. have had several test and yet to have a diagnosis other then ibs when i know thats not what it is. this week i will be swallowing a camera pill so that they can look at my small intestines since they couldnt find anything with the colonoscopy and the upper endoscopy but i do know that one of the big problems was from taking ant acids for far to long. So my nutritionalist put me on a suppliment called gastracid and digestive enzymes. and it did help. now i no longer eat enough to take them but will again when i am able to get back on solids. i can really relate to what your going through. my pain is constant and i am now so mal nourished i can barely function and its making me incredibly anxious. one thing that helps with the pain is achupuncture. id definatly look into alternative meds because eastearn medicine and drs have been around far longer. and western docs are simply so obsessed with money. in the medical society if your not wealthy you dont deserve to be healthy. i hate it so much and feel quite hopeless at times.
