I Have Gallbladder Problems, My Gallbladder Is Not Emptying Like It Should, Will This Cause A Rupture If Not Removed And Does It Cause Swelling Of The Abdomen, Feet And Ankles?

I Have Been Having Gallbladder Attacks, Have Gone Thru The Ct Scan, The Radio-active Scan, It Shows That My Gallbladder Is Not Emptying Right, So I Need It Out, Have Experienced Swelling, abdomen, feet&ankles??? My feet and ankles have been swelling really bad, I am on a water pill and at night the swelling does not go away, or could this swelling be caused from certain medications?? I have had the Ct scan,the radio-active scan and blood work done, the Gallbladder shows during these test that it does not empty properly. Do you have any answers for me? Peggy Blankenship
