What it is
Migraine is a long-term brain condition, not just a bad headache. In migraine without aura, attacks usually bring a moderate to severe headache along with other symptoms, but there is no aura beforehand. It used to be called common migraine.
You can have attacks with aura and attacks without aura at different times. Attacks may happen once every few years or several times a week.
Symptoms
- Throbbing or pounding pain, often on one side of the head
- Pain that gets worse when you move, walk or climb stairs
- Feeling sick or being sick
- Finding light, sound or smells hard to bear
- Pain severe enough to stop your normal activities
How an attack unfolds
-
Hours to a day before
Warning stage
Tiredness, yawning, stiff neck, mood changes, food cravings, thirst or needing to pass urine more often.
-
4 to 72 hours
Headache
Throbbing pain with sickness and sensitivity to light and sound. Medicines work best taken early.
-
Hours to 2 days after
Recovery stage
Feeling drained, foggy or low, sometimes called a migraine hangover.
Not everyone has every stage, and they can overlap.
Triggers
Attacks often happen when several triggers add up. Common ones are irregular sleep, missed meals, not drinking enough, stress or the let-down after stress, alcohol, too much or too little caffeine, hormone changes, and bright or flickering light. Some things that seem like triggers, such as craving sweet food, are really early signs of an attack.
Keep a headache diary
Write down each attack, how long it lasted and what you took, along with your sleep, meals and periods. Eight weeks of diary helps your doctor and supports a funding application. Download our free printable diary.
Treatment
During an attack
Simple painkillers
Pharmacy or supermarket
Aspirin, ibuprofen or paracetamol, taken as early as possible in the headache. Aspirin and ibuprofen usually work better than paracetamol for migraine.
Triptans
Prescription, and some from a pharmacist
Medicines made for migraine, as tablets, melts, nasal sprays or injections. If one doesn't suit you, another often will. They aren't suitable for people with heart or circulation disease.
Anti-sickness medicines
Prescription
They ease sickness and help your body take in other medicines during an attack.
Gepants
Specialist or GP, depending on your area
Newer tablets for people who haven't been helped by at least two triptans, or who can't take triptans and haven't been helped by simple painkillers.
Watch how often you take painkillers
Taking acute medicines on more than 2 days a week can lead to medication overuse headache, which makes headaches more frequent. If you need them that often, ask your GP about preventive treatment.
Preventing attacks
Preventive tablets
Usually from your GP
Considered if you have 4 or more migraine days a month, or attacks badly affect your life. Options include beta-blockers such as propranolol, amitriptyline, topiramate and candesartan. They are started at a low dose and built up. Give each one at least 3 months at a good dose before deciding. Topiramate and sodium valproate can harm an unborn baby: they must not be used in pregnancy, and anyone who could become pregnant needs highly effective contraception while taking them.
CGRP medicines
Specialist, after GP referral
Monthly or 3-monthly injections, a hospital drip every 3 months, or daily or every-other-day gepant tablets, that block a chemical involved in migraine. On the NHS they are usually offered once at least 3 preventive tablets haven't worked.
Nerve blocks
Specialist clinic
An injection of local anaesthetic, sometimes with a steroid, at the back of the head. It can calm migraine for a few weeks to around 3 months.
Supplements and devices
Usually self-funded
Riboflavin (vitamin B2), magnesium and coenzyme Q10 help some people. Nerve stimulation devices such as Cefaly, gammaCore, Nerivio and sTMS can be bought privately but aren't on the NHS for migraine.
When to get urgent help
Call 999 if you have
- a sudden, extremely bad headache that peaks within minutes
- weakness, numbness or a drooping face on one side, or slurred speech
- sudden loss of sight
- confusion, drowsiness or a seizure (fit)
- a high temperature with a stiff neck or a rash
- a headache after a head injury
Call NHS 111 if
- an attack lasts more than 3 days
- your symptoms are very different from usual
See your GP if
- attacks are becoming more frequent or severe
- you need painkillers on more than 2 days a week
- your treatment isn't working
- migraine is new for you and you're over 50
Work and your workspace
Migraine can count as a disability under the Equality Act 2010 (the Disability Discrimination Act in Northern Ireland) if it has a substantial, long-term effect on your everyday life. Conditions that come and go still count, and the law looks at how you would be without treatment. If it applies, your employer must make reasonable adjustments.
Adjustments that often help
- Flexible hours and working from home on bad days
- Regular short screen breaks
- A quiet, dark place to rest and take medicine
- Time off for appointments
- Flexibility over migraine-related absence
A migraine-friendly workspace
- A chair with good lumbar and neck support
- A desk big enough to put your screen at arm's length
- Screen raised so the top is at eye level
- A flicker-free monitor with an anti-glare or blue-light filter
- Lighting without flicker or glare, and blinds to control daylight
Access to Work can pay towards equipment and support. Acas and Citizens Advice give free advice on your rights.
How The Beyond Pain Foundation can help
If NHS waits are too long, or the help you need is not available to you on the NHS, we may be able to fund:
- A private appointment with a headache specialist to get a treatment plan sooner
- A trial of a nerve stimulation device your doctor recommends
- A course of nerve blocks or acupuncture from a qualified practitioner
- Workspace equipment that removes triggers, such as a supportive chair, a larger desk and screen filters
Every award depends on your situation and the funds we have that month. A letter from your doctor, a headache diary and a written quote all help your application.
