Update. I had my ERCP Sphincterotomy on Friday. The surgeon cut the muscle of the Sphincter of Oddi and cleaned out my duct. I did however have extreme abdominal pain about 8 hours later and had to go to the ER to ensure it wasn't Pancreatitis. I started feeling better shortly after arriving at the ER. Blood tests were good and was sent home. They suspected I passed a stone after the Sphincter was opened or experienced a spasm. Since then the PCS seems to be improving a lot. In the spirit of not getting too confident I will update in another month. Thanks for your input everyone but so far so good.
