Most people with migraines should start with their primary care physician. A general practitioner can diagnose migraines, prescribe both acute and preventive treatments, and manage the condition effectively for the majority of patients. Only a minority of migraine cases need a specialist, and knowing when to escalate can save you months of unnecessary waiting.
Start With Your Primary Care Doctor
Primary care physicians diagnose migraines based on your symptoms, medical history, and a physical exam. There’s no blood test or brain scan that confirms a migraine. Instead, your doctor checks whether your headaches match established patterns: attacks lasting 4 to 72 hours, pain that’s pulsating and usually on one side, moderate to severe intensity, sensitivity to light and sound, and nausea. If you’ve had at least five attacks fitting that profile, you meet the formal diagnostic criteria.
Your primary care doctor can also prescribe first-line treatments. For stopping an attack in progress, anti-inflammatory medications and triptans are the standard options. For prevention, several types of daily medications can reduce how often migraines occur, and your doctor may also recommend magnesium supplements at 400 to 600 mg daily, which have evidence behind them for reducing migraine frequency. Many people get their migraines under good control at this level of care and never need to see a specialist.
One important thing your primary care doctor does is rule out dangerous causes. Red flag symptoms like a sudden, explosive headache unlike anything you’ve experienced, headaches with fever, confusion, vision loss, weakness on one side of your body, or headaches that started after a head injury all require urgent workup. These situations may call for imaging or an emergency department visit rather than a routine specialist appointment.
When to See a Neurologist
A neurologist becomes the right next step when your migraines are diagnostically unclear, hard to treat, or complicated by other conditions. Specific situations that warrant a referral include:
- Treatment failure. You’ve tried standard preventive and acute medications without adequate relief.
- Chronic migraine. You’re having headaches on 15 or more days per month for at least three months, with migraine features on at least 8 of those days. Chronic migraine is significantly harder to manage and usually requires specialist input.
- Unusual symptoms. Your migraines come with motor weakness, brainstem symptoms, prolonged aura, or other features that make the diagnosis uncertain.
- Frequent attacks requiring escalation. If you’re having migraines two or three times a week, using acute treatments for each one can lead to medication overuse headaches, creating a worsening cycle. A neurologist can build a preventive strategy to break that pattern.
Neurologists can order MRI or CT scans when needed to rule out structural problems like tumors, bleeding, or other brain conditions. They also have access to a broader range of treatments, including injectable preventive medications given monthly or quarterly, neurotoxin injections approved for chronic migraine, and non-medication approaches like biofeedback and neuromodulation devices.
Headache Specialists: The Next Level
A headache specialist is a neurologist (or occasionally a physician from another specialty) who has completed an additional year of fellowship training focused entirely on headache disorders. These specialists are certified through the United Council for Neurologic Subspecialties, which requires at least 12 months of dedicated headache medicine training with 80% of that time spent in supervised clinical practice. Their fellowship must include at least one neurologist on the core faculty.
You’d seek out a headache specialist for the most stubborn cases: migraines that haven’t responded to multiple treatments, complex patterns involving multiple headache types at once, or situations where medication overuse has become entangled with the original migraine disorder. Comprehensive headache centers, as described by the American Migraine Foundation, typically bring together headache-trained neurologists, psychologists, physical therapists, and nutritionists who collaborate on a treatment plan addressing medications, lifestyle, mental health, and physical conditioning all at once.
These centers are particularly useful if you’ve become physically deconditioned from chronic pain, or if anxiety and depression have developed alongside your migraines, which is common. A physical therapist at a headache center can teach targeted exercises for pain relief, while a psychologist may use cognitive behavioral therapy to address the way chronic pain reshapes daily life.
Children and Teenagers With Migraines
Children get migraines too, and the first stop is their pediatrician. Pediatricians follow the same general approach as adult primary care: diagnose based on symptoms, try first-line treatments, and refer when needed. A pediatric neurologist is the appropriate specialist for children whose headaches include red flags like waking from sleep with headache and vomiting, headaches that are progressively getting worse in frequency or severity, headaches with neurological symptoms like weakness or vision changes, or headaches that don’t respond to standard treatments. Personality changes, a sudden drop in school performance, or confusion with headaches also warrant prompt referral.
Navigating Insurance and Referrals
If your insurance plan requires referrals, you’ll typically need your primary care doctor to send you to a neurologist before you can see a headache specialist. Beyond referrals, insurance often creates another hurdle called step therapy. Before covering newer migraine medications, most insurers require documented evidence that you’ve tried and failed older, cheaper treatments first. For newer acute treatments, that usually means trying at least two triptans. For newer preventive medications, insurers typically want to see that you’ve tried at least two standard preventive drugs for 8 to 12 weeks each.
Some plans also limit coverage to a single medication from certain drug classes, which can be a problem if your treatment plan involves both a preventive and an acute medication from the same category. And if a newer preventive medication successfully reduces your migraine days from, say, 12 per month down to 2 or 3, switching insurance plans can create a frustrating catch: the new insurer may deny coverage because your current migraine frequency is too low to meet their threshold, which often starts at 6 to 8 migraine days per month.
Knowing this ahead of time helps. Keep detailed records of every medication you’ve tried, how long you took it, and why it didn’t work. This documentation is what your doctor needs to fight prior authorization denials.
How to Prepare for Your Appointment
Whichever doctor you see, arriving with a headache diary dramatically improves the visit. Track at least a month’s worth of headaches before your appointment, recording the date and time each headache starts and stops, what you were doing and what you ate or drank beforehand, the location and severity of pain, any accompanying symptoms like nausea or visual disturbances, what treatments you tried and whether they helped, and the real-world impact of each attack (missed work, canceled plans, time spent in bed).
This information does two things. It gives your doctor the data needed to confirm a migraine diagnosis and distinguish it from other headache types. And it reveals patterns you might not notice on your own, like headaches clustering around certain foods, sleep changes, or points in your menstrual cycle. A doctor working from a detailed diary can make treatment decisions in a single visit that might otherwise take months of trial and error.
