Migraine headaches are another common cause of forehead pain. The exact cause of migraines is not known but it appears to be an interplay of genetic and environmental factors leading to changes in brain hormone levels. The pain tends to be worse on one side of the head although it can occur on both side.
Some of the more common triggers for headache are lifestyle related, such as poor diet, stress, muscle tension, and lack of exercise. Serious underlying disorders, such as brain tumours, are rarely the cause of headache, although persistent headache should always be investigated by a doctor. Headache can be classified into two broad categories: primary and secondary. Examples of primary headache include cluster and tension headaches.
