Migraine headaches are congestive headache. They begin with extreme vasoconstriction in the affected hemispheres and the excess pressure will press against the meninges causing excruc iating pain. In classic migraines the pain will be preceded by blurred vision, the perception of flashing lights followed by extreme throbbing pain on one side of the head. Migraines will often be accompanied by hypersensitivity to light, nausea, vomiting and may persist from several hours to several days.Once a migraine has begun, little can be done except to wait for it to pass.Most treatment protocols focus on prevention.  For those who suffer frequent, debilitating migraines, some medical options now are available to take on a prphylactic basis. Taken daily, these medicines will prevent the initial onset of a headache.
Alternate treatments involve a cool cloth to the head to reduce blood
flow in conjunction with a warm foot bath for a derivative hydrotherapeutic
effect. A warm dark room and lots of quiet is also recommended. Massage therapy as part of a maintenance routine is advised.
