I would highly suggest a hida scan. It was worth the money and tells you of your gallbladder function. Mine was working at under 1 % so it had virtually stopped working from chronic infection, adhesions and the such. The U/S showed everything was normal, no stones. I had acalculous cholecystitis, ie, without stones. After I had my gb out in October it was near rupture. I am glad I had it out, but I still suffer symptoms, nausea, pain, etc. I am sure my liver is congested and need it flushed. I am working on that now. I hope you find out some more answers, try the flush. It may help you.
