Overview

Almost everyone gets headaches, and the overwhelming majority are primary headaches — the headache is the condition, not a symptom of something else. Tension-type headache and migraine account for most of them.

A small minority are secondary — caused by something identifiable, occasionally something serious. The purpose of a consultation is to sort one from the other, which a careful history does reliably and which is why this assesses well remotely.

Three things are worth flagging at the outset, because each is common, treatable, and repeatedly missed:

  • Medication overuse headache. Taking painkillers on more than 10 days a month causes headaches rather than relieving them. This is the single commonest reason occasional headaches become daily ones
  • Cluster headache. Excruciating, one-sided, around the eye, with a red watering eye and blocked nostril. It has specific and highly effective treatment — and it is routinely misdiagnosed as migraine or sinus trouble for years
  • Carbon monoxide poisoning. Headaches affecting several people in the same house, or that improve when you are away from home and return when you come back. This is rare, easily missed, and lethal

Common symptoms

Tension-type headache — the commonest of all

  • Pressing or tightening, like a band around the head
  • Both sides
  • Mild to moderate — you can usually keep going
  • Not made worse by walking or climbing stairs
  • No nausea, no significant light or sound sensitivity
  • Often associated with neck and shoulder tightness

Migraine

One-sided, throbbing, moderate to severe, worse on movement, with nausea and dislike of light and sound. Disabling. See migraine for the full picture.

Cluster headache — the one that gets missed

  • Excruciating pain, strictly one-sided, around or behind the eye
  • Lasting 15 minutes to three hours, up to several times a day
  • On the same side: red watering eye, drooping eyelid, blocked or running nostril
  • Restlessness — people pace, rock, or cannot keep still. This is the clearest distinction from migraine, where people lie down and stay still
  • Often strikes at the same time each night, and comes in clusters over weeks separated by long remissions

It is far more common in men, and the average time to correct diagnosis is measured in years. If this describes your headaches, say so explicitly — there is specific treatment that works.

Medication overuse headache

Present on most days, usually there on waking, in someone taking painkillers regularly. Often started as migraine or tension headache and became daily.

Causes and risk factors

Common causes of primary headache

  • Stress and mental tension
  • Poor sleep, or disrupted sleep patterns
  • Dehydration and missed meals
  • Caffeine — both too much and withdrawal. Withdrawal headache is why so many people get headaches at weekends and on holiday
  • Alcohol
  • Posture, prolonged screen work, and neck strain
  • Eye strain — genuine, though less often the cause than assumed. An eye test is reasonable if headaches are related to close work
  • Hormonal change around periods

Secondary causes worth knowing about

  • Medication overuse — painkillers on more than 10 days a month, and codeine-containing preparations are the worst offenders
  • Carbon monoxide poisoning — from faulty boilers, gas fires or blocked flues. Symptoms include headache, nausea, dizziness and confusion, and the giveaway is that they improve away from the house and affect other people or pets in it
  • Temporal arteritis — over 50, with scalp tenderness, jaw pain on chewing and visual change. Sight-threatening and urgent
  • Sinusitis, dental problems, and jaw joint dysfunction
  • High blood pressure, though only when very high
  • Raised pressure inside the head — headache worse lying flat, on coughing, or waking you from sleep
  • Medication side effects, including nitrates, some blood pressure drugs and the combined pill

How it is diagnosed

Headache is diagnosed by history. There is no test for primary headache, and scanning is normal — which means imaging cannot make the diagnosis and is only useful for excluding specific concerns.

The questions that do the work

  • Onset — gradual or instantaneous. A headache reaching maximum intensity within seconds is an emergency
  • Pattern — constant, episodic, or in clusters; the same each time or changing
  • Duration — minutes, hours or days. This separates cluster from migraine from tension-type more efficiently than anything else
  • Site and character — one side or both, throbbing or pressing
  • Associated features — nausea, light sensitivity, watering eye, blocked nostril, aura
  • What makes it better or worse — movement, lying flat, coughing
  • How many days a month you take any painkiller. This one question identifies medication overuse headache, and it is frequently not asked

A headache diary

Four to six weeks of dates, timing, duration, severity, medication taken and cycle position. It is the most useful investigation available for headache, costs nothing, and repeatedly shows patterns — particularly medication overuse — that nobody had recognised.

When imaging is indicated

Not for typical primary headache with a normal examination. It is warranted for a thunderclap onset, new headache over 50, a clear change in an established pattern, headache worse lying flat or on straining, persisting neurological symptoms, or new headache in someone immunosuppressed or with a cancer history.

Blood tests

Inflammatory markers urgently where temporal arteritis is suspected; full blood count and thyroid function where the picture is unclear.

How we treat it online

Headache is well suited to remote assessment — diagnosis is by history, and treatment is a conversation and a prescription. What we cannot do is a neurological examination or fundoscopy, so where the history raises concern we arrange in-person assessment rather than working around it.

Tension-type headache

  • Simple analgesia used sparingly — and the ceiling matters more than the choice of drug
  • Addressing the drivers: sleep, hydration, caffeine, stress, screen setup and neck posture
  • Amitriptyline at low dose for frequent tension-type headache, which works on pain signalling rather than as an antidepressant and is genuinely effective as a preventive
  • Physiotherapy where neck and shoulder tension is prominent

Cluster headache

Ordinary painkillers are useless here — attacks peak before a tablet could work. The treatments that do work:

  • High-flow oxygen through a non-rebreathe mask, which aborts most attacks within minutes and can be arranged for home use
  • Injectable or nasal sumatriptan, which works far faster than tablets
  • Verapamil as prevention during a cluster period, which requires ECG monitoring and specialist involvement

If your description fits cluster headache, we refer to neurology — and we say so clearly, because being told for years that it is sinusitis is a common and avoidable experience.

Medication overuse headache

The treatment is withdrawal of the overused painkiller. That means a genuinely difficult two to four weeks in which headaches worsen before improving markedly.

It is far more achievable with a plan, a defined start date, a preventive started alongside, and someone to check in with. We will not simply tell you to stop — we will set it up properly, because doing it unsupported is where most attempts fail.

Referral

Neurology referral for cluster headache, diagnostic uncertainty, headaches not responding to two adequate preventives, or any red-flag feature.

Important

When to seek urgent help

Call 999 for:

  • A sudden severe headache reaching maximum intensity within seconds to minutes — a thunderclap headache. This can be bleeding around the brain and needs assessment immediately, even if it settles
  • Headache with a stiff neck, fever, dislike of light, or a rash that does not fade under a glass — possible meningitis
  • Headache with weakness, numbness, facial droop, slurred speech, confusion or difficulty walking
  • Headache with a first seizure, or loss of consciousness
  • Headache after a significant head injury, particularly with drowsiness or repeated vomiting
  • Headache with confusion or drowsiness in more than one person in a household — suspect carbon monoxide. Get everyone out into fresh air and call 999

Seek same-day assessment for:

  • New headache over 50, with scalp tenderness, jaw ache on chewing, or any change in vision. Temporal arteritis permanently threatens sight and treatment must not be delayed
  • Headache with a painful red eye and haloes around lights — possible acute glaucoma
  • Headache that is consistently worse lying flat, on coughing or straining, or that wakes you from sleep
  • New headache in anyone with a cancer history or a weakened immune system
  • Headache in pregnancy with visual disturbance, swelling or upper abdominal pain — contact your maternity unit
  • A headache that is clearly different from your usual pattern

Book a routine consultation if: headaches occur on more than a few days a month; you take painkillers on more than 10 days a month; headaches disturb sleep, work or family life; or your description fits cluster headache. All of these have treatments.

Prevention and self-care

The four things that prevent most ordinary headaches

  • Regular sleep — same times, including weekends
  • Regular meals — do not skip; low blood sugar is a common trigger
  • Consistent fluid intake through the day
  • Consistent caffeine. Not necessarily none — but the same amount daily. Sudden reduction causes withdrawal headache, which is why they appear at weekends and on the first day of a holiday

The rule that matters most

Do not take painkillers on more than 10 days a month. Above that, they cause headaches rather than treating them. Track it honestly — people routinely under-count, because a tablet taken at work does not feel like a dose.

Avoid codeine-containing painkillers for headache entirely. They are the most likely to cause medication overuse headache and the hardest to withdraw from.

Desk and screen

  • Screen at eye level, feet flat, forearms supported
  • The 20-20-20 rule — every 20 minutes, look 20 feet away for 20 seconds
  • Get up and move at least hourly; sustained neck posture is a genuine cause
  • An eye test if headaches relate to close work — free on the NHS for many people

A safety point worth acting on

If you get headaches at home that ease when you go out, or others in the household have them too, have your gas appliances checked and fit a carbon monoxide alarm. They cost very little. This is uncommon but it kills people, and the pattern is the only clue.

NHS or private

The most valuable and least welcome thing about frequent headaches is free: the painkillers may be causing them.

Medication overuse headache develops when painkillers are taken on 10 to 15 days a month or more — and it is common, under-recognised, and produces exactly the pattern people describe as chronic daily headache. The treatment is stopping the painkillers, which makes things worse for a few weeks before it makes them better, and almost nobody attempts it without being told what to expect.

Simple analgesia and a headache diary cost almost nothing, and the diary is genuinely the most useful diagnostic tool here — more so than any scan.

Your NHS GP treats headache free, and NHS neurology is free on referral.

Private brain imaging is heavily marketed for headache and is rarely indicated. NICE recommends against neuroimaging solely for reassurance in people with a normal examination and no red flags — the diagnostic yield is very low, and incidental findings generate their own anxiety and investigation.

Where a consultation is genuinely worth paying for is getting the diagnosis right — tension-type, migraine, cluster and medication overuse are managed completely differently — and reviewing whether preventive treatment is warranted.

What needs emergency assessment: a sudden severe headache reaching peak intensity within minutes; headache with fever, neck stiffness or rash; headache with weakness, confusion or visual loss; new headache after 50; or headache worse lying down, on coughing, or first thing in the morning.

Evidence and guidelines

NICE CG150, Headaches in over 12s: diagnosis and management, is the governing guideline. It sets out diagnostic criteria for tension-type headache, migraine, cluster headache and medication overuse headache, and recommends a headache diary for at least eight weeks to support diagnosis.

CG150 defines medication overuse headache as occurring with use of triptans, opioids or combination analgesics on 10 or more days a month, or simple analgesics on 15 or more days a month, and recommends abrupt withdrawal with warning that symptoms worsen initially.

CG150 recommends against neuroimaging solely for reassurance in people with a normal neurological examination.

CG150 lists the red flags requiring urgent or emergency assessment, which underpin the features above.

NICE NG12 covers headache features warranting urgent brain imaging for suspected malignancy.

Common questions

Do I need a brain scan?

Almost certainly not. Primary headaches — tension-type and migraine — are diagnosed on history, and a scan is normal in both, so it cannot confirm anything. Scanning is reserved for specific warning features. A normal scan also does not make headaches less real, which is a common and unhelpful assumption.

Why do I wake up with a headache every day?

Three possibilities are worth checking. Medication overuse is the commonest — count your painkiller days honestly. Sleep apnoea causes morning headaches, particularly with snoring and daytime sleepiness. And rarely, headache worse on waking and on lying flat can indicate raised pressure inside the head, which needs assessing.

Can painkillers really cause headaches?

Yes, and it is one of the most under-recognised problems in headache medicine. Regular use — more than 10 days a month — changes how the brain processes pain and produces a persistent daily headache. The only treatment is stopping, which is hard for two to four weeks and then markedly better.

Is it my eyes?

Less often than people assume, but it is worth excluding, particularly if headaches follow close work or reading and sit around the eyes and forehead. An eye test is quick, often free, and rules it in or out.

Could it be my blood pressure?

Usually not. High blood pressure does not generally cause headaches unless it is very high indeed, and the belief that it does leads people to check their blood pressure when they have a headache — finding it raised because they are in pain and anxious. It is worth measuring, but it rarely turns out to be the explanation.

How do I know if it is a cluster headache?

Three features together: excruciating one-sided pain around the eye, lasting under three hours, with a watering eye or blocked nostril on that side — and, crucially, being unable to keep still. Migraine sufferers lie down; cluster sufferers pace. If that is you, say so, because the treatment is completely different and highly effective.

What about carbon monoxide?

Worth taking seriously if headaches occur at home and improve when you are away, particularly if anyone else in the house — including pets — is affected. Get gas appliances serviced and fit an alarm. It is rare, but it is one of the few headache causes that is both entirely preventable and fatal.

Is caffeine good or bad?

Both. It can relieve a headache in the short term and cause one on withdrawal. What matters is consistency — a steady daily amount is fine, while cutting back sharply on a Saturday produces exactly the weekend headache people blame on stress.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
