Acid reflux post gallbladder removal

Can anyone help me here? I had my gallbladder out about 6 weeks ago. It was had a 27% ejection fraction (which is low) and I also had a polyp in the neck of the gall bladder so they needed to take it out for that reason. I had acid reflux symptoms before the surgery (did not know that they were acid reflux then). Since the surgery the symptoms have been much worse. About up to 4 1/2 hours after eating I get mostly very sharp pain between the shoulder blades. I also have pain in right side (where gallbladder was) and left side and general mid abdomen tenderness. I feel nautious when I wake up sometimes and sometimes throughout the day. I also feel somewhat breathless when I have the attacks some times. I have also been to ER with these symptoms and had countless EKG's, been given nitro glycerine but they do not think they are cardiac related. I was on Nexium for two weeks 40 mg, then was moved to Protonix for just over two weeks and now on Prilosec for 3 weeks - no improvement. Have also tried Pepcid AC at night. I am at my wits end. Is it Acid Reflux? Is it something else? Could it be Bile Reflux. It concerns me because I have lost weight because I am eating so little as I find it so hard to find anything much easy to eat that does not give me these symtoms. Has anyone been on Erythromycin? Thanks
