Look beyond the confines of head pain and observe any accompanying symptoms that accompany your headache. Migraines often bring forth a barrage of additional manifestations, including nausea, heightened sensitivity to light and sound, visual disturbances such as the appearance of bright flashing lights, pins and needles sensations radiating down one or both arms, or bouts of dizziness. If you find yourself devoid of these supplementary symptoms, it is more likely that you are dealing with a tension headache.
