From your latest update, it does sound like it must be trigeminal neuralgia. What I'd suggest as a next step is to keep a diary so you know the dates - continue riding as you would but note down the following:
- Lunge beforehand for 15 minutes - one a scale of 1-10 (10 being utterly unrideable), how much does she shake?
- Note weather conditions - wind speed, sunny/cloudy, pollen count, rainfall (should be easy enough to google all this for where you are)
- Note if your horse is in heat here too
- Note the time when you start and the time when you stop lunging
- Then note what kind of riding/where you are doing it (e.g. hack for x amount of time, indoor school for x amount of time) and again give a score from 1-10 at the end of the ride.
Try to use the same tack/equipment (so if you're going to use the nosenet, make sure you always do so, including when lunging at the start).
You might not see any pattern at all but if you're lucky, you'll see what specific conditions trigger the worst shaking. I would at that point go to your vet as they'll be able to prescribe appropriate medications.
It's worth mentioning that often headshaking will almost completely disappear over winter. If the horse is one of those, you'll find out in a few months and often melatonin will help as it tricks the horse's brain into thinking it's a different time of day/year and that can be enough to solve the problem.
Magnesium can help in some cases but not others and it can have quite a few side-effects. If you go this route, it's a good idea to get your vet to monitor levels so you can see if any changes actually correlate with this at all. Magnesium is involved in nerve signalling, which is why it can help - but if the horse wasn't deficient to start with, it's not going to. It may also be antagonistic to other substances that the horse needs for nerve function (like potassium) so a balance is more important - but it's all guesswork if you don't have a baseline test first.
Something else they can do is give you medicines that are intended to manage neuropathic pain so that even if you can't figure out the trigger, you can deal with the pain itself.
It definitely could be related to hormonal cycles and it's normal for it to be linked to pressured situations. The main idea is that situations like that (and exercise itself) cause physiological changes that are triggered via the autonomic nervous system - for example the dilation of blood vessels or stimulation of the vagal nerve to increase heart rate. So a horse with a malfunctioning trigeminal nerve simply "misinterprets" these things and instead perceives pain.
