Well, as I have figured it out the stiff neck causes headache. The origin of the lesser occipital nerve is painfull, I have been working on the sub-occipital musclegroup, with variable effect.

TriggerPoints = ok, working a little on them to relieve pain, but not primary.

Tension could be a multi-aspect case as he earlier suffered a serious concussion from a snowboarding accident, which did heal in 4 weeks (2,5 years ago), now this paraglider accident and then stress at work. The sleep problems became evident about 1/2 year after the paraglider accident.

No exercises pain at all.

No cracking neck when doing range of motion exercises - I have tested flexion, extension, rotation and joint play segmentally from C0 to Th2, a little stiff in the lower cervical, but no "locked" joints.

Temporomandibular joint = no pain, but can not but opens only 5 cm, which I think isn't full. This can be due to the nightly biting. No spastic pterygoidus as I can see.

But what about the dreams?? When facing such patients one wants to "take it by the root", it would have been interesting to find out about this.. I have heard once that if you have stomach-pain you will dream bad dreams, anybody who has heard it? .. Is it possible to find out more about it?
