In my case, migraines also cause nausea and vomiting.
I always had my migraine medication with me, but once the symptoms start, you can't hang around - all you want to do is lie in a darkened room, so I would be forced to leave work and go home. I felt trapped, physically and mentally, because quite often I developed a migraine whenever Robert and I did anything like go out for dinner.
The first injection was effective within just a couple of days.
Although I wasn't convinced that these would help, I would have tried anything.
The injections were behind my ear and were quite painful, but they were over quickly.
Over the years, I've been to my doctor many times and tried countless treatments, from painkillers and anti-inflammatories to nostril inhalers.
But nothing got rid of them, although the migraine medication Triptans helped a little.
I could tell they didn't understand and didn't approve of me taking so much time off.
Migraine affects the whole body - not just the head.
Then, when I was in my early 50s, my GP learned of a new headache clinic at the Royal United Hospital in Bath and referred me to Dr Nicola Giffin, a neurologist.
She suggested treating me with nerve-block injections to reduce the frequency of the attacks and relieve the pain.
My husband, Robert, was at work until the early evening, so I had to care for the children during the day, even if I had a migraine. When I turned 40, I was suffering attacks two or three times a week, and while they were eventually diagnosed as migraines, my doctor still could not explain why they were becoming more frequent.
