Migraines can occur for a variety of reasons, including reduced blood circulation to the brainstem and the base of the head, to a possible genetic reason, and with abdominal migraines mostly common in children there is as of yet no known reason.

CranioSacral therapy can address many of the reasons that cause headaches and migraines. The light pressures used in treatment reduce pressure to the muscles around the face and head, improve the blood flow to all parts of the brain, reduces stress in people and is often able to effectively treat pain which has no diagnosable causes as in abdominal migraines.

In particular improving restricted motion of the neck and base of the head enables improved blood flow both into and out of the skull so improving the body's ability to deal with increased intra cranial (within the head) pressure and to help remove and drain any fluids which are no being leaving the skull in a normal way.
