Bile duct spasms are typically associated with gall bladder removal.
though there are cases where the spasms have been experienced in those
with their gall bladders.  More common in men than in women, the
actual cause is unknown.  The symptoms are very similar to that of
gall bladder disease pain with burning in the upper GI tract which
radiates to the back and between the shoulder blades.  These spasms
and burning sensations are thought to be caused by contractions of the
common bile duct (the duct that allows bile from the liver into the
small intestine) or a tightening of the Sphincter of Oddi the muscle
opening that controls the flow of bile and pancreatic enzymes into the
small intestine. From researching, it appears the the dysfunction is
typically associate with the Sphincter of Oddi.  I have provided
additional information below covering Sphincter of Oddi Dysfunction
(SOD).

If you are experiencing any of these symptoms, seek a physicians
attention immediately as they may be signs of something more serious,
including, but not limited to stones in the duct.

Thank you for your question and I hope the above information has been
helpful.  If you need any additional clarification, please let me know
