We tried FCR, functional cranial release in March, 2013. We watched this doctor slow the clicks and heard them stop!!!! This is not a cure, but it is the best thing we have tried to date. My son only clicks now when he swallows, yawns and sneezes. He still has pain but not all the time. THis procedure was done by Dr. John Lieurance. He works will all kinds of movement disorders. You can witness some of what he does by looking at clips on u-tube by looking for palatal myoclonus. We also recently became aware of a FaceBook page for PM suffers. It is an active web link with lots of information. If you suffer from PM, you might want to join that group and try FCR. It was a miracle for my son. WE have a long way to go, but we are now headed in the right direction.
