Having pain with Gallbladder and all tests were normal

I have had pain and diarrhea after eating for years. Lately I have had severe pain after eating under my right breast and ribs. I was admitted into the hospital and a series of tests. Hida scan, ultrasound, cat scans that were all normal. The MD found sludge in my Gallbladder. What do I do now? I spent a few days in the hospital on morphine and IV’s with no answers. What next?
I need help.
Thank you
