Gallbladder problems/surgery

Ok so for the past few months I have been suffering from severe abdominal pain, nausea, and vomiting. The pain has been getting worse and worse. And now my back is starting to hurt.

My gastroenterologist did many tests but they all came back normal. But bc of my symptoms and where the pain is located when he presses on my stomach he fully believes that it is my gallbladder. He says that there are cases where no matter what the tests say there are still problems with the gallbladder.. So he sent me to surgeon who basically poked around and said he doesn't know what is wrong and won't do anything.

My bfs mom is an rn and she also believes that this could be the problem. She also told me that there are cases where the test results are fine but the gallbladder is still causing problems. And that they do surgery. So I don't understand why the surgeon won't do anything. I have all the symptoms of it being a gallbladder problem. And my gastro said that he believes that its the problem.

Have any of had any of these symptoms?

Do any of you have any idea what might be going on?
