I had the exact same pain 2 months after my gall bladder surgery only to find out that the kidney stone that was stuck in my kidney had came lose from the kidney and became lodged in my ureatha...(mind you I was told it was so small it would stay there or cause little or no pain.) The kidney urology doctor told me that was most likely the cause of my pain after analyzing my stone and said that I probably did not need to have my gall bladder taken out..however having my gallbladder taken out did help with other pain and problems I was having. I just want to say I know what it's like. I had went 5 years with doctors not fixing the problem. However today I feel great and hopefully you will be able to feel that way to. Please just push your doctors till they find what the pain is from.
