Aura migraines ?
I've had vertigo and at first it came on like a migraine, but with vomiting, light sensitivity. (Normally I get 'Aura' migraines and don't vomit).
A week later I went from feeling pretty good to head spinning so bad I couldn't even sit partway upright without vomiting. Noise set off the vomiting, light set off the vomiting. Turned out to be 'vertigo' - ended up being taken in an ambulance, rehydrated on a drip, senior ER doctor saw me after about 12 hours and was very unimpressed that they'd also given me a couple of doses of valium to calm me down a little...
Tests didn't turn up anything, except the possibility of it being set off by a virus. Took a week before I started to improve, three weeks before I could drive a car, and I would not wish vertigo on anyone...
I was prescribed lots of stuff (heavy duty migraine drugs, anti-emetics) but they really didn't seem to make any difference.
Aura migraines are something different. I get loss of peripheral vision, squiggly lines across my vision, tingling in my hands which moves upwards over time to my face, and usually when the tingling fades the headache hits in the opposite side of my head. I've also had migraines that affected my speech and balance.
Mine are definitely set off by hormonal changes, also weather changes - my dad, sister and I all have the same pattern and we can call each other and say 'Oh, did you get a migraine today'... if we are located in the same city...
I was told one theory is that they are caused by changes in the blood vessels supplying to the brain, and that it's possible they are more serious than perhaps imagined.
The difference with the vertigo and the migraine is that with the vertigo my head would spin on a certain 'plane' and then if I tilted my head the slightest bit, it would start to spin in a different direction... whereas with a migraine, unfortunately, the headache is the same...and only fades over time - it takes me 24-48 hours before the headache fades after a migraine.
One thing that works for myself, my dad, my sister is taking paracetamol before the headache hits. Because we get 'aura' migraines the onset of the headache is after 1-2 hours of symptoms...so the strategy that works is to take paracetamol as soon as symptoms appear, and also eat and drink, so the drugs are absorbed properly. Seems to work. Don't know why. We've certainly done the range of other much more heavy migraine drugs with little success. I never take painkillers, except for this purpose, so it's not a 'rebound' headache but I also don't have any resistance...
