Whenever I have a migraine, during the long hours of lying in the dark waiting for the agony to abate, there's a lot of time to think. One thing that always pops into my mind is an old sketch from The Catherine Tate Show.
Tate's foul-mouthed character Nan is setting the world to rights in a doctor's waiting room, when an ill-looking woman pipes up.
"I'm sorry, do you mind keeping it down? I suffer from terrible migraines..."
"Oh, I am sorry sweetheart I feel terrible for you. Don't feel you've got to explain anything to me. I feel dreadful. Would you like a mint?"
"I just need to see the doctor."
"Yeah, you go and see the doctor sweetheart, yeah. He'll sort you out. Aaaaaah."
At this point, the migraine-sufferer is called in by the doctor.
Then Nan lets rip.
"WHAT A F***ING LIBERTY! She's got HEADACHE! Sat in a doctor's surgery with a headache. Oh they want SHOOTING THEY REALLY DO."
When I have to cancel plans or call in sick because of my old adversary, I suspect that some people think I'm making a bit of a fuss over a headache. Having spent Good Friday and Saturday alternating between my sickbed and the bathroom floor, I'd like to remind everyone who isn't one of the eight million sufferers in Britain that a migraine ISN'T JUST A HEADACHE.
Not only is there the pain and the spavined vision, there's vomiting, and numbness too. As The Migraine Trust explains on its website, a migraine is a "complex neurological condition". Do spread the word. I tried to when I crawled to the chemist to get prescription migraine tablets, and the pharmacist made "helpful" suggestions as I waited. Had I tried painkillers? I'd rather just go straight for a gun, I said, trying for a friendly explanation of how I was feeling but ending up sounding insane.
Because the pain of a migraine does make me go a bit mad: whether it's fantasising about clawing my eye out or relieving the pressure with a spot of hand-drilling directly into my cranium.
The madness – and the pain – has subsided now, and I shudder to think of how the people who get migraines once or twice a week cope. Mine are every few months and look at the fuss I make. But if there's one thing you could do, when you next hear a colleague or friend has had one (and there are 190,000 migraine attacks every day in the UK), it's to say "poor you" rather than, "ooh, headaches are awful, aren't they?"
