Migraine in pregnancy can be relieved by acupuncture, according to the results of a small Italian pilot study lead by the Women’s Headache Center at the University of Turin. Twelve patients in their first trimester were given six treatments over four weeks. Migraine intensity, nausea and vomiting episodes all decreased significantly over the course of the treatment period.
Migraine in general is looked at more fully under Headaches and Migraine.
