Not all headaches
are caused by tension.
It could be hormones or
food allergies (check your diet).
It could be neurological.
Seek medical advice.

Going back over the anatomy (refer to the "what is..." page). . .
Picture a tough membrane (the meninges) lining the inner layer of your skull, continuing down the inside of
your spine, and attaching to your sacrum.  Imagine it looking like a tadpole-shaped water balloon.  This forms
a container for your brain and spinal cord (central nervous system).  It also contains the cerebrospinal fluid,
which buoys and bathes the central nervous system, providing nutrients, carrying away waste, maintaining
electrolyte balance and aiding neurochemical communication.
All these parts have measurable, rhythmic motions.  The fluid has a tide-like motion.  Your brain actually
expands and contracts!  The 22(ish) bones in your skull are mobile.  The joints (sutures) between many of
them are designed to accommodate all that motion.

Re the headaches. . .
About 95% of the blood flow from your head has to come out through two holes in your skull (the jugular
foramina).  They are located roughly an inch or so in from your earlobes towards each other.  The jugular
foramina are in the sutures (joints) between your temporal bones and your occiput.  Any compression in these
joints, between the bones, or in the surrounding musculature, can decrease the blood flow through your
jugular veins, causing back pressure.
Sharing the jugular foramina are two cranial nerves:  the accessory nerve and the vagus nerve.  The
accessory nerve runs to two muscle groups which run from the base of your skull to your shoulders.   They
are the shruggers:  the sternocleidomastoid and trapezius.  The vagus nerve (“vagus” means “wanderer”)
runs to your thoracic and abdominal organs, notably, in the case of migraines, your stomach.
Are you getting the picture?  They’re all tied together.

What needs to happen?
The idea is to create a little elbow room for your jugular veins, vagus nerve and accessory nerves.  This is
done by helping the base of your skull decompress.  When the muscles and connective tissues in that area
soften, and the temporal and occipital bones ease off of each other a bit, it frees the blood flow and
decreases the nerve compression.
