update for PM: research FCR, functional cranial release. Dr. John Lieurance works on all movement disorders and he actually got the clicking to stop!!!!! My son still has pain and we are working on that but it is 100% better than before now that the clicking has subsided. He still gets clicking but only when he swallows, sneezes or yawns. No more constant over 100 clicks per minute in each ear. One LARGE step in the right direction. No drugs...please check it out. Also we recently became aware of a large group of PM suffers on FaceBook. Check it out.
