You can have gallbladder pain but not show any signs of gallbladder problems. If you're not (doctor quote) "Fair, Fat and over Forty" they may not check for it. However, I had gallbladder problems off and on for a year. I noticed that when my Cellcept was increased for my swollen joints and hands my gallbladder problems eased off. My personal guess is that the gallbladder is responding to all the inflamation in my body and also being inflamed, but since there are no gall stones and it still works, nothing shows up.
