Hi Sammas,
I also sympathise. I always had migraines and they got worse after my first period and persisted until my last. I thought I would get rid of them after menopause, they have virtually disappeared, but now I have chronic daily headache and just mild symptoms migraine-related like high sensitivity to lights, smells and sounds, but one symptom has actually got worse, tinnitus. The suggestions given by the other ladies are really helpful. I try to release tension (whatever you like to do that relax you), avoid computer, TV, tablets, mobiles, eat bland meals, avoid too much caffeine (can't stop cold turkey or it can worsen the headache), drink plenty of water, avoid direct sunshine and strong scents, amongst a number of other details! It's tricky, because the brain is controlling everything else and when the brain suffers the whole body is affected, not the mention the mind!
Regarding preventative meds, I take cinarizine, prescribed off-licence by Neurologist, but only for a couple of months if headaches don't stop. Your headaches sound clearly hormonal so this might not really helpful.
I hope you can get it sorted out soon.
