I'm another in the "go to the doctors" camp but when I started getting migraines in my 30s and did go to the doctor expressing concern about brain tumours, he did say that brain tumours rarely come and go so if a headache appears out of nowhere and then goes, you probably haven't got a tumour.
Mine were work stress-related and, like Piperade, I was prescribed a very low dosage of beta-bocker for 6 months which broke the cycle of migraines. Previously I'd been getting them about every 3 weeks. Further fuel for the
"go to the doctors" recommendation was supplied this week by a friend whose daughter was incapacitated by a migraine for 4 days (no previous history of migraines) which was eventually diagnosed as a leaking aneurism. She was a heavy smoker from about the age of 13, though, and hospital opinion is that smoking definitely contributed to the problem if not totally caused it.
Migraines aren't necessarily completely debilitating with flashing lights and violent vomiting; mine used to last for 3 days, was a low grade ache over one eye (the side varied and sometimes changed over the 3 days) but I did get nausea with them which was pretty depressing.
I don't know how old you are, ClaireLouise, but sometimes the onset of migraines in middle age has been shown to pre-date natural menopause by about 10 years. Something jolly to think about there.
