How to Get Referred to a Headache Specialist

The referral does not get decided by how bad your migraines are. It gets decided in about ten minutes, by a GP who has your file open, on the strength of what you can tell them in that window.

Which means the preparation matters more than the asking. Someone who arrives with a treatment history and two numbers gets a referral letter written the same day. Someone who arrives saying the headaches have been terrible lately gets another prescription and a review in eight weeks, and neither of them is being treated unfairly.

The routes that actually exist

There is a common belief that you have to fail some fixed number of drugs first. Failing preventives is one route, not the only one.

The Migraine Trust’s page on headache clinics lists the reasons a GP may refer: doubt over the diagnosis, the possibility of a rarer form of migraine, other headaches present alongside the migraine, treatment that is not working well, attacks getting worse or more frequent, and your own request for a referral. That last one is on the list, and most people do not know it is. “A rarer form of migraine” is also doing more work there than it appears: vestibular migraine, where the attack is vertigo and there may be no headache at all, is commonly investigated as an ear problem for years before anyone reads it as migraine.

The three-preventives version is a real convention rather than a rule, and it is the strongest hand when you have it. If you have tried three preventive drugs at proper doses without benefit, say so in those terms and you are describing something the guidelines already have an answer for.

In England, the framework a GP works within is NICE’s guideline on headaches in over 12s. Elsewhere the routes differ — in the US, referral often runs through insurance rules rather than a national guideline — so check what applies where you are before leaning on any of it. What holds everywhere is that a referral letter needs facts in it, and you are the only source of most of them.

The sentence that supplies a reason

A GP writing a referral letter needs to put something in the “reason for referral” field. Give them one, out loud, in the first thirty seconds.

“I’ve tried amitriptyline and propranolol, both up to the full dose, for four months each, and I’m still at fourteen headache days a month with nine of them migrainous. I’d like to be referred to a headache specialist.”

That does four things. It names the drugs, states the doses were reached, gives the duration, and provides the two numbers — then asks plainly. Compare it with “nothing’s really working and I wondered if I should see someone”, which contains no fact anyone can write down.

If the preventive history is short, use whichever other route fits. “The pattern has changed since March — they’re twice as frequent and the aura is different from what I used to get” is a diagnostic-uncertainty referral, and it is a stronger one than a medication history.

What to take in

Four things, on one page.

Migraine days and total headache days per month, averaged over the last three months. Days rather than attacks, counted the way a chronic diagnosis is counted, because an attack spanning two dates is two days and that distinction moves people across thresholds.

Acute medication days per month. Ask yourself the honest version of this before someone else does. If the number is high it strengthens the case for referral rather than weakening it, and under-reporting it is the most counterproductive thing you can do in the room — the thresholds and why they differ by drug class are in medication overuse headache: how many days is too many.

Every preventive you have tried: name, highest dose reached, how long you stayed on it, and why you stopped. This is the section that decides the letter, and it is the one people prepare worst. “Something beginning with T that didn’t work” cannot be referred on. A drug abandoned at a low dose after two weeks and a drug that failed at full dose after four months lead to completely different next steps.

What it is costing you. Days of work lost, things you have stopped doing. A validated score is better than a description here, and both MIDAS and HIT-6 take two minutes.

What to bring to a neurologist appointment sets out the same page in more detail; the GP version is identical, just earlier in the queue.

Get the diary started before you need it

Three months of ordinary logging is what turns all of the above from an estimate into a lookup. It is also the thing you cannot produce retrospectively on the morning of the appointment, which is when most people discover they need it.

Six fields a day, one of them a tick on the clear days so the record produces a rate rather than a list. The free printable diary is laid out for it, and Migraine Journal keeps the same counts on a rolling thirty-day window if you would rather not add up columns by hand.

Start it now even if you are not sure you want a referral yet. The version of this that goes badly is always the one where the appointment arrives first.

If the answer is no

Ask two questions before you leave.

“What would change your mind?” You want a threshold: another preventive, a specific number of days, a period of tracking. A named condition is something you can meet and come back with. An unexplained no is not.

“Could I have that in writing?” A documented refusal is more useful than a vague maybe, because it is what makes the next step reasonable rather than dramatic — a different GP in the same practice, the practice manager, or in the UK a request for an out-of-area referral to a clinic with a shorter wait, which The Migraine Trust notes is worth asking about when the local list is long.

Keep the tone flat throughout. You are assembling a record, not winning an exchange, and the person across the desk is usually not the obstacle. They are working from what is in front of them, which is exactly the thing you can change.

None of this is medical advice, and a referral is a clinical judgement rather than an entitlement. If your headaches have changed in character, come on suddenly and severely, or arrive with new neurological symptoms, that is not a referral conversation — it is a reason to be seen now. The rest of the appointment guides cover what to do once you have the date.
