ok, what's next?...

I'm a generally healthy, 32 year old male. For approx. 9 months now I've been having pain and swelling in the RUQ abdomen. To date I've had a normal ultra sound, normal CT scan, and normal HIDA scan.  I'm having no other symptoms...no bleeding, diarrhea, constipation, weight loss. Just the swelling..generally after a meal, the type of meal doesn't really matter except that high fiber seems to make me a bit gripier. After a bout of swelling/pain which is nearly every day but sometimes less severe, I'm sore just under my rib cage. Ibuprphen helps the swelling a great deal,  but i won't allow my self to take too much of it because I'm on medications that cause liver stress already (zocor, lotensin) as preventative measures due to family history. (ok, I need the lotensin).
OH,  i've also had several normal liver function tests as well.
My symptoms keep pointing to gall bladder desease,  but nothing's found to this point...  so, what's next?  what should I ask my doctor to do next? what else should I consider?
Any suggestions are greatly appreciated.
Louie
