Visual disturbances
Visual disturbances are often experienced in conjunction with the beginning of an intense headache or migraine. Indeed, approximately one third of migraine sufferers experience auras. Auras can consist of flickering lights, light halos, or bright spots that usually appear at the onset of a migraine, but can also appear before or during the migraine as well. With migraines causing severe pain and sensitivity to sound, sensitivity to light and inability to see properly can make migraines even more difficult to live and deal with.
