Wow lots of replies there, thanks for those.
Funnily enough Pellegrino I DO have bruxism, I had a michigan splint made for me many moons ago. But unfortunately it didn't do much other than protect my teeth, it was supposed to discourage the grinding. The osteopath seemed to think my pain was coming from my neck/occipitals though.
"My Neurologist" lol - never been offered one Mick! But now I have some spare pennies (and insurance) I might get myself one, see if they can't sort out my drug regime. I'm sorry you have so many, that sounds very hard to deal with. 
Candestartan noted Denby, thanks. And thanks for the link to the film Kralia, will have a look at that.
No alcohol at all Atrocious, haven't had a drink since long before the headaches started!
SpacePotato, I'd dearly live to be a runner but exer ise certainly induces headaches - never been able to exer ise before work or anything, too risky. I do walk my dog a few miles a day, although I have to do it across several shorter stints which he doesn't seem to mind. I can generally limp a mile around the block with a headache (I'll either pay for it, or it'll make it go away), but if I can't DH will take over.
New job 100% desk based and utterly terrifying - I'm excited but it is going into areas I've never dealt with before at a high level, so one is shitting oneself at the same time. Will look up some pilates stretches.
Oh I do drink water, just not in the wild quantities people seem to believe is mandatory these days. I was born in the 70's and you never used to see kids surgically attached to drink bottles and adults gulping from the tap every few seconds. A few glasses is ideal, more if you're exercising hard, but I can't ascribe to the 4 litres a day brigade. I only referenced the tea and Pepsi in terms of caffeine intake!
Always been fascinated by the botox nerve blocks SapatSea, I think I'm going to push for a referral and lean on my insurance. I wonder if my policy permits referrals from private GPs...hmm, probably not. That means speaking to "I'm a male doctor" again.
I don't really know if I'm in full menopause or not, but my symptoms - irritability/mood swings, mild incontinence, pain with intercourse, hot flushes etc - were enough to get me onto the Estrogel. I have a mirena coil and haven't had periods for 11 years, so nobody knows. Bloods inconclusive, but Estrogel made a big difference to me.
Sometimes with a headache I get flushing on one side of my face?
