Well, its probably too early to be using the word 'success', but I'd say I'm somewhat better than I have been. I suffer from what I believe to be menstrual migraines. I must say that I'm nowhere near as bad as many of you people who post here, and I do read with horror some of the posts about daily or weekly migraines, and so my experiences are somewhat minor compared with yours. Nevertheless, getting a regular monthly migraine that lasts about 4 days in total is not nice and I have tried to do something about it.
About 6 months ago, I bought some progesterone cream. I used it for a couple of months (last 2 weeks of cycle, as directed), with no success whatsoever. I then thought I'd try oestrogen cream. I bought that, used it (just before and during period) for a couple of months with success, but found that it only delayed the migraine until I stopped using the cream. This led me to believe that the oestrogen was (at least partly) the culprit. For the last couple of months, I went back to the progesterone cream. I've also been very careful about having no alcohol and making sure I do neck stretches/exercises for my "stiff" neck. I've stopped using all analgesics except for occasional aspirin. I have been migraine-free for the last 2 cycles.
I don't yet feel sufficiently confident to say that this is the solution for me, but I'm certainly going to continue with the progesterone. It also makes me feel more human, with fewer PMS symptoms.
I thought this was worth reporting and may help someone else out there.
