Why do painkillers not work any more?
Most likely medication overuse headache. Taking any acute painkiller on more than 10 days a month — or a triptan or codeine-containing drug on more than 10 — causes the brain to produce more headaches, not fewer. The way out is to stop the overused drug, which involves a difficult two to four weeks and then a marked improvement. It is worth doing with support rather than alone.
Do I need a brain scan?
Usually not. Typical migraine with a normal examination does not require imaging, and a scan cannot diagnose migraine — it is normal in migraine. Scanning is indicated where there are specific warning features: a changed pattern, onset over 50, headache worse lying down or on coughing, or persisting neurological signs.
Is aura dangerous?
Aura itself is not, and it fully resolves. It matters for two reasons: it must be distinguished from a stroke — aura builds over minutes and goes away, a stroke starts suddenly and persists — and aura means you should not use combined hormonal contraception, because of the stroke risk when the two combine.
Is it hormonal?
For many women, substantially. The oestrogen drop just before a period is one of the strongest triggers known, and menstrual attacks tend to be longer and more severe. Migraine often improves in pregnancy and worsens through perimenopause before settling afterwards. Targeted treatment around the period works well.
Are chocolate and cheese triggers?
Probably not in the way people think. Craving chocolate is frequently part of the prodrome — so the attack was already beginning and the chocolate got the blame. The evidence for dietary triggers generally is much weaker than for irregular sleep, missed meals and dehydration.
What if the triptan does not help?
Try taking it earlier — timing is the commonest problem. Then try a different triptan, since response varies considerably and there are several. Then add an anti-sickness tablet, which improves absorption. Most people who conclude triptans do not work for them have tried exactly one, once, taken too late.
Can migraine be cured?
Not cured, but very often well controlled — and current preventive treatment, including the newer CGRP drugs, is considerably better than what was available a decade ago. Many people find attacks become less frequent with age, and migraine commonly improves after the menopause.
Should I just push through?
No. Migraine is not something to be endured with willpower, and continuing to function through an attack tends to prolong it. Treat early, stop, rest — and if attacks are frequent enough that you are regularly having to push through, you need a preventive rather than more determination.
