Hi everyone. I had a Hida Scan yesterday, and was diagnosed with Sphincter of Oddi. They haven't said what is causing the blockage in the bile duct. I am waiting for the doctor to call back. My question is, can my GI Doctor perform the procedure that needs to be done to take care of this. I have been sick since March and have had all the test, and have lost 13 pounds. I am in constant pain everyday. Does this need to be done right away, as they are backlogged here and I want to get this taken care of as soon as possible. Thank you for any info you can give me. By the way, I have been underweight all my life and this loss of weight has caused me to be so tired. I can't get out of my own way.
