hida scan

Hi I went for a cck hida scan today.  at first they almost couldn't do the part of the test where they injected you with the nuclear medicine and i asked why.  he said during the first hour when they inject u with something that makes your gall bladder fill up that my gall bladder was filling up a little bit then emptying right away.  he told me that is not normal.  can u please tell me why you think or why possibly my gall bladder is doing that?  i've gone for every test possible to see what is wrong with my stomach and every test has come back fine.  I don't have gall stones and they said my gall bladder is fine.  the reason my dr. sent me for this test was to see if my gall bladder was contracting the way it should be.

If doctor doesn't know...it's hard to say anything, since we don't see the results and what really happened.
