Hi!
I would definately investigate sphincter of oddi dysfunction!
You sound very similar to me! I have had every test under the sun done and all show "normal", I too had my gallbladder removed and it was inflamed! This has not helped anything at all!
I am investigating the SOD theory at the moment......
Good luck

Have you had colonoscopy, endoscopy? Sometimes people develop SOD after gallbladder surgery which is a narrowing of the bile ducts maybe they can check you for that I hear that can be quite painful and feel just like a gallbladder attack? Hope you feel better.
