Is Hyperkinetic Gallbladder real?

[azman878]

Upper RQ pain, comes and goes for the last year and a half, but getting worse the last two months.  Sometimes it spreads around to the back, and my right shoulder hurts now too.  US was normal, other than a small polyp on the gallbladder.  ALT liver enzyme level was a bit high last month, but has come down to almost normal levels now (63).  HIDA scan showed 88% EF.  GI doc and surgeon both said this was fine, but reading a lot of anecdotal evidence on the internet that an EF this high, may be just as bad as having an EF too low.  This seems like new evidence, so a lot of docs aren't on board with this yet.  I don't know what to do at this point.  Scared of having my GB removed, only to have no change and then not have a gallbladder anymore.  Would like to keep all my internal organs where they are!  Any southern California docs know about this?

Forgot to mention, also having nausea on and off as well the last few months.
