About 1 in 5 migraine sufferers experience an aura. An aura is considered a warning signal that a migraine is about to start soon. In some cases, an aura appears during or after the migraine episode. An aura lasts 15 to 60 minutes. Classic visual aura symptoms are: Seeing bright flashing dots Seeing bright flashing lights Blurred vision Experiencing blind spots Having temporary vision loss Seeing jagged or wavy lines Auras can affect different senses too, such as: Ringing in the ears (tinnitus) Arm tingling Face tingling Speaking difficulties Changes in smell (such as strange odors) Changes in taste Some neurological auras are very rare and specific, and include: Temporary paralysis, or neurological or sensory changes on one side of the body (hemiplegic migraine). At the beginning of the headache, temporary dizziness, numbness, or vision changes can also occur. Partial or complete temporary loss of vision in one of your eyes (retinal migraine). This type of headache occurs with a dull ache behind one of your eyes that spreads to the rest of your head. Sudden vertigo, double vision, loss of balance, and slurred speech occur before the headache (migraine with brainstem aura). These severe symptoms are often accompanied by pain in the back of your head, vomiting, tinnitus, and inability to speak. A rare and severe migraine that lasts more than 72 hours (status migrainosus). Medication withdrawal can cause this type of migraine syndrome, and nausea and headache pain can be extremely severe.
