Has anyone experienced Median Arcuate Ligament Syndrome

My daughter was diagnosed with Median Arcuate Ligament Syndrome after gallbladder surgery failed to correct extreme abdominal pain. She had an MRCP which showed this.  She also has been on pain med for almost a year for pain from damaged tailbone from childbirth....which won't seem to heal.  The gallbladder didn't show to be diseased or have gallstones according to an ultrasound....but further testing showed that it was only functioning at 10%.  
I would like to know if these two problems could be caused by lack of adequate blood supply to the tailbone and gallbladder due to Median Arcuate Ligament Syndrome,
