Migraine Treatment in Tempe, AZ

What the Research Actually Shows

​

The neck's connection to migraine has real science behind it. Sensory nerves from the upper neck and the trigeminal nerve — the nerve most directly involved in migraine pain — converge on the same relay point in the brainstem, called the trigeminocervical complex, so signals from the neck and from migraine pain pathways interact directly at a neurological level. People with migraine also show measurable, examinable differences in neck range of motion and pressure sensitivity compared to headache-free people, across a review of 35 studies and over 2,400 participants. That's why I treat the neck as a genuine part of every migraine evaluation, not an afterthought.

​

Chiropractic care itself has been tested for migraine directly, not just inferred from the anatomy. Trials from 2000 and 2017 found meaningful reductions in migraine frequency, duration, and medication use in patients receiving spinal manipulative therapy compared to control groups. It's a smaller body of research than what exists for migraine medication, and results vary somewhat between studies, which is typical for an approach that's still being actively researched. What it tells me clinically is that chiropractic care helps a meaningful share of migraine patients — not everyone the same way, which is why your plan gets built around your specific pattern rather than a generic protocol. Our post on why the upper neck matters in migraine goes into the full research, including where it's strongest and where more work is still needed.

Where Magnesium Fits In

​

Magnesium comes up constantly in migraine care, and there's a real reason for that. During an acute attack, roughly half of migraine patients test low on ionized magnesium even when a standard total-magnesium blood panel looks completely normal — which is exactly why a normal result on routine bloodwork doesn't rule this out. Magnesium's job in the nervous system includes keeping the NMDA receptor blocked, which holds calcium out of the cell; when magnesium runs low, that block comes off, glutamate's excitatory effect increases, and the neuronal wave called cortical spreading depression — the mechanism behind migraine aura — spreads more easily. Low magnesium also affects trigeminal nerve signaling and blood vessel tone, both directly relevant to migraine physiology.

​

That evidence base is strong enough that the American Academy of Neurology and American Headache Society gave magnesium a Level B rating in their 2012 guideline update on migraine prevention — meaning it's probably effective and should be considered for patients who need preventive therapy. The dose studied is typically 400-600 mg of magnesium oxide daily, and that's worth a second look before you assume it's the right form. Magnesium oxide is one of the least absorbed forms available — one pharmacokinetic study found a fractional absorption of only about 4%, compared to roughly 9-11% for salts like magnesium chloride or lactate, and a direct head-to-head trial found magnesium citrate reached significantly higher serum and urinary levels than oxide from the same dose. That poor absorption is exactly why oxide is what pharmacies stock for constipation — the unabsorbed magnesium sits in the bowel and pulls water in with it. At 400-600 mg a day, most patients feel that in their gut before they feel it in their head. I typically move patients toward a better-absorbed form, like magnesium glycinate — we break down why oxide, citrate, and glycinate behave so differently in the gut in this research review — so you're actually getting therapeutic levels without the GI trade-off. Diet is part of that same picture — see our post on magnesium-rich foods for where to start.
