I have Sphincter of Oddi Dysfuncfion. It causes severe upper abdominal pain, a lot like a gallbladder attack. I was misdiagnosed for ten years and have still had problems, pain that required medication and the ER every once in a while. The pain has suddenly gotten so much worse. I also struggle with Pseudo Tumor Cerebri which causes massive headaches. I am getting spinal taps every 5 weeks, they do not work on the headaches but we are trying to keep me from going blind from the Sphincter of Oddi.
