All Migraines are headaches.  However, only about 7 percent of headaches are migraines.
The effect of a migraine is extreme sensitivity to light and sound, nausea, and possibly vomiting.  Migraines last from 4 to 24 hours, and range in severity from painful to absolutely debilitating.
Current treatment includes resting in a dark, quiet room, sleeping and chiropractic adjustments.
About 90% of non-migraine headaches may be triggered by muscle tension and definitely can be helped by chiropractic adjustments.
