Pressure application device and method for ameliorating migraine headache

A portable system for substantially compressing an extracranial blood vessel on a user's head, said system including:

• a foldable pressure application device comprising a constant force biasing member, two foldable elongated arms connected by a hinge to said biasing member for transmitting the constant force as substantially constant pressure, and a pressure applicator connected to each said arm for applying the substantially constant pressure to the head of the user to thereby aid in compressing the blood vessel when said pressure application device is properly positioned on the head;
• and
• a substantially pocket sized carrying case for carrying the pressure application device with said two foldable arms in a folded position.

A method of substantially compressing a temporal blood vessel on a person's head, the method comprising the steps of:

• producing a constant force in a biasing member connected to two force transmitting arms by a hinge;
• and
• applying the force on the temporal blood vessel as substantially constant pressure by positioning the two force transmitting arms on the person's head so as to apply pressure to the temporal blood vessel.

A method of treatment during a pre-headache stage of a migraine, the method comprising:

• producing a constant force in a biasing member connected to two force transmitting arms by a hinge;
• and
• applying the force to a temporal, blood vessel as substantially constant pressure during the pre-headache stage of a migraine by positioning the two force transmitting arms adjacent the temporal blood vessel so as to apply the force as pressure thereon.
