Suggest Treatment For Pain In Upper Abdominal Area

I have mild to moderate pain from the upper left side of my abdomen (under my ribs) that comes out the left side of my back. - I feel nauseated and eating first makes it feel better then I feel even worse. - I m female. Have light-headedness. 46 yrs old. Type I Diabetic. Told have borderline gallbladder (the doctor wanted me to have it out - but don t know what borderline means, can guess). I have gastroparesis and also dairy problems (go into shock when having any kind of milk or lactose containing products). - The doctor told me she doesn t care about that pain... so, is it not related to this sickness I feel? The problem started last September, and have lost about 70 pounds from not eating very much. (Still fat, so doctor isn t worried.). - Have had endoscopy - said everything looked normal, except red colored lining in there. - Last time I drank alcohol, I had something like this - lasted for about a week, but went away. - Don t know if it helps, but I thought I d mention it.
