What is a skillful way to meditate in the midst of a migraine headache?

> When the Bod-hisattva Quan the Am, who has been such a source of > inspiration of peace workers in Viet- nam, saw into the reality of the > five aggregates giving rise to emptiness of self, she was liberated > from every suffering, pain, doubt, and anger. -- The Miracle of Mindfulness, p. 48 I have been practicing mindfulness for less than a year. I have had some deep experiences and found benefit. However, when I have a migraine headache my mindfulness feels completely useless. Any guidance or any good resources that would teach me to practice my mindfulness in the midst of a bad headache would appreciated.
