Migraine With Aura: What It Is and When to See a Doctor
Migraine aura causes visual, sensory or speech symptoms before or during an attack. Here is what is normal, what to track, and the warning signs that need a doctor.
What is migraine aura?
Migraine aura is a set of temporary, reversible neurological symptoms that appear before or during a migraine attack — most often visual, but sometimes affecting sensation or speech. About one in three people with migraine experience aura, at least occasionally. The symptoms typically build up over 5–20 minutes and last less than an hour.
Aura is not the headache itself. It is a separate phase, and some people get the aura without much head pain at all.
The three main types of aura
- Visual aura (the most common) — zigzag lines, flickering or shimmering spots, a blind spot that spreads, or flashes of light. It usually affects both eyes, not one.
- Sensory aura — tingling or “pins and needles” that spreads slowly, often from the hand up the arm to the face.
- Speech or language aura — trouble finding words or slurred speech.
A key feature of true migraine aura is that symptoms spread gradually and then resolve completely, usually within 60 minutes.
Why tracking aura matters
Aura is worth recording in detail because it changes the clinical picture in two important ways:
- It affects medication choices — for example, migraine with aura is a reason to avoid combined (estrogen-containing) hormonal contraception, because the combination raises stroke risk. See our guide on hormonal contraception and migraine.
- A change in your usual aura pattern is something a doctor needs to know about. Tracking gives you a reliable baseline to compare against.
For every attack, note whether an aura came first, what type it was, how long it lasted, and whether it resolved fully.
When aura is a warning sign — see a doctor
Most aura is benign, but some patterns need prompt medical attention. Treat the following as red flags:
Seek medical advice urgently if: the aura comes on suddenly at full intensity (rather than building up), symptoms affect only one eye, weakness or numbness on one side does not fully resolve, it is your first-ever aura after age 50, or the symptoms last much longer than an hour. These can mimic or signal something other than migraine.

How Trackwell helps
The Trackwell migraine tracker has a dedicated field for aura — type, duration, and whether it preceded the headache — so you build a clear baseline and can show your doctor exactly how your aura behaves over time.
