Many times, migraine headaches are preceded by some sort of visual disturbance known as an aura. They usually occur anywhere minutes to hours before the pain of a migraine starts. These symptoms typically last for anywhere from 10 to 25 minutes. The aura may occur without actual pain, and in these cases it is known as a migraine equivalent.

Visual changes can occur in one or both eyes. They can include one or more of the following:

  • Zigzag lines
  • Flashing lights
  • Visual hallucinations
  • Temporary blind spots (scotomas)
  • Light sensitivity
  • Blurred vision
  • Eye pain
A migraine may not be accompanied by a classic aura, but a number of other symptoms may signal the onset of a migraine headache.
  • Loss of appetite
  • Nausea
  • Vomiting
  • Chills
  • Increased urination
  • Increased sweating
  • Swelling of the face
  • Irritability
  • Fatigue
