If the osteopath is going to do cranial sacral work on you, I would be very hesitant to spend the money. If he only uses some of the cranial sacral techniques but does not do the "cranial reading" he might be worth a try.

Cranial reading or diagnosing is done by feeling your skull. From that they believe they can diagnose many maladies in the whole body. They also claim to be able to move the cranial plates. Odd, since they are fully fused by about 20 years of age, much earlier in most people.

The important area to get diagnosed is the atlas to occiput or occipital condyle.(Occiput-Atlas Joint )

There is a diagnostic technique to determine if this joint is out. While lying on your back, the physician has you drop your chin to your chest by only moving at the OA joint, not any of the lower neck vertebra. If you nose goes off center, there is a restriction in the OA joint. They also do a range of motion test from side to side measuring how many degrees of rotation you have to the right and left.

You have an opportunity to interview some physicians or their staff to find one who has skills to diagnose the OA joint. NUCCA chiros and Low Force Technique or Minimal Force technique chiros often have these skills.

Good luck with your treasure hunt. If you find the right physician, he/she will be a treasure.
