I cannot comment much on the
gallbladder, but I CAN tell you that you should not take
Yaz on account of your previous colicky
gallbladder, nor should you be on any birth control pill because of your age, too much risk for heart problems. Switch to birth control with foam and rubbers, done correctly it's more effective than the pill. Since a doc said the pain in URQ was pulled muscle, you can go with that.
