Some people with a migraine experience aura.
The most common auras are visual, such as flickering lights, spots, or lines. “You may see a little jagged line…that will develop some cross hatches, and it might sort of move in a curved direction,” Dr. Calhoun says.
Auras typically last between five minutes and an hour, with a 60-minute “skip phase” before the headache pain sets in, she says.
Some patients have auras without a migraine-type headache or any headache at all.
