If your symptoms last for longer than this then you are experiencing a prolonged aura, these are not uncommon for those who have migraines. 10 to 30% of people with migraine experience migraine with aura*. Some people may experience aura symptoms alongside the headache, or for some no headache will happen after the aura has taken place. How frequently you experience a migraine aura can change depending on your circumstances, you could experience them once a month or once a year.
What are the symptoms?
Migraine auras tend to affect your vision, causing irregularities that can be distressing, such as:
- Flashing lights
- Sparkles or stars

- Blind spots
- Tunnel vision
- Geometric shapes
- Temporary blindness
It is also common to experience sensations in one of your arms or legs, such as tingling or pins and needles; this can also lead to numbness. These feelings can move from your hand up your arm and to your face; you may experience tingling in your face, tongue or lips.

Can you cure a migraine?

What migraine treatments are available?
There medications that you can buy over the counter in your local pharmacy and our Pharmacists will also be able to offer expert advice. Many people find that painkillers, such as ibuprofen or paracetamol can help to ease the pain of a migraine headache, however these are best taken at the first signs of an aura, before a migraine happens. This way they can be absorbed into the body before the headache starts, if they are taken later than this they may not have time to take effect before your symptoms worsen. Make sure to always read the packaging instructions and the enclosed patient leaflet before you take any painkillers.
However if you find that over the counter tablets are not helping to manage your symptoms, you should see your GP. They’ll be able to offer stronger medication, such as triptans or anti-sickness medicines, as well as more advice to help improve your symptoms. You may need to use a combination of medications to ease your migraines or decrease the symptoms of auras.
Migraine auras can differ from person to person, however common symptoms include vision disruptions such as flashing lights as well as feelings of confusion or dizziness. You might find that a migraine happens after the symptoms or that you can experience an aura without ever having a migraine.
There are a number of factors that can cause migraines, from environmental to hormonal changes and stress is one of them. Stress is something that most of us experience at one time or another, and managing your stress levels can help to alleviate migraines. This could mean that you switch off your phone for an hour a day to give yourself a break, or you have a bath before bed. Making some time to relax should become part of your day, and you shouldn’t feel guilty for looking after yourself, these little changes could help you to avoid a migraine attack too.
Migraine auras can last anything from five to 60 minutes. If your symptoms last for longer this is referred to as a prolonged aura. Very rarely, people experience aura symptoms that last for days or longer.
