Kentish you have all my sympathy and more !
Not having been a headdachey -sic person as soon as I hit 50 and the menopause, wham !
I was awakened every morning at about 3am with the most excruciating pain I'd ever experienced. I'd rather have had a dozen babies than go through that again.
I was downing paracetamols like sweets but they had no effect on the pain. I was banging my head on the wall then turning up for work like a wet rag.
After 7 weeks of it I finally went to the GP who had me admitted to hospital then I was transferred to the neurological hospital. Scans,tests galore-----nothing so the neuro-surgeon said it was a problem with the " basement and not the attic " which he dealt with.
Back to the GP who prescribed Dixarit but they were making me too drowsy for work so I started buying migraleve and they weren't doing much either ,so in the end I took Imigran.
The thing was, when I got these migraines they made me heave/wretch and after that happened the migraine went-----only to return again at 3am ?
They went on for a few years with the same pattern of the early hours.
I actually went on a long-haul flight after having been up half the night-----how I did it I'll never know but I just dosed myself up to the hilt.
I remember taking 2 paracetamol every 2 hours ! I got to a stage I couldn't have cared less so long as the pain went and didn't return.
They did go as quickly as they'd come on and fortunately I haven't suffered a headache since, in years. It's a miracle I'm here at all with all that I took. Honestly I wouldn't wish them on my worst enemy------and I can withstand pain.
