Raff;

A hidascan can be helpful in diagnosing a sluggish gall bladder, one which does not properly empty as it should. Your symptoms, although very uncomfortable and awful for you to deal with at times, are surprisingly not life threatening. (I know it can feel that way, though). If you are able to deal with this problem and do not wish to have surgery, then there is not much reason to go forward with a hidascan if you do not want to. If, however, your symptoms are severe enough that you would consider surgery if the test showed an improperly functioning gall bladder, then go ahead and have the test.
