According to Healthline.com, a migraine is a headache. Migraines are highly disabling and typically only occur on one side of the head. According to the Mayo Clinic, a headache refers to pain in any area of the head, occurring on one side of the head or both sides.

According to Healthline.com, headaches are generally classified as either primary headaches or secondary headaches. A migraine is a primary headache. In addition to pain experienced in the head, migraines may also be accompanied by nausea, vomiting and heightened sensitivity to light or sound. Other types of primary headaches include cluster headaches and tension headaches. According to Healthline.com, secondary headaches are more serious than primary headaches because secondary types are typically indicative of serious health problems or underlying conditions, such as a tumor or brain aneurysm.
