Quick update. I have been off work over 6 weeks post surgery trying to get into a pain management routine to return to work next week. My GP prescribed me 10 mg Dicyclomine an anti spasmic medication taken 30 mins before a meal. So far it has helped with some of the pain and discomfort. Eating smaller portions as I did before the surgery is helping as well. My wait for a HIDA scan of the Sphincter of Oddi continues. Meanwhile my liver and pancreas blood tests are normal so that is a relief. Still hoping this is just a matter of slow healing and not dysfunction of that Sphincter. My GP tells me the PCS in many cases will subside in time if the Sphincter function is normal. I sure hope so.
