I honestly believe that all my problems are related. First my gallbladder quit working (no stones), then one year later my sphincter of oddi and now my stomach. I have to wonder if there is a smooth muscle disorder they have not recgnized yet because they are all looking at each event seperately. I would be willing to bet that most people with GP pain have oddi dysfunction. Once they fixed that on me, the only GP symptoms I faced were/ are Nausea, fullness and bloating.
