Why This Topic Matters

Almost everyone experiences a headache at some point in life. For many people, headaches are occasional, short-lived and improve with rest, hydration or simple pain relief.

However, headaches that continue for days, occur repeatedly over weeks or begin changing in frequency or severity deserve closer attention. For this reason, they should never be ignored.

One of the biggest misconceptions is that headaches are either “just stress” or “something serious”. In reality, most persistent headaches fall somewhere between these two extremes.

The role of a GP is not simply to prescribe medication. Instead, a GP aims to understand why the headaches are occurring, identify any underlying contributing factors and determine whether further investigation or specialist referral is required.

Seeking medical advice early often provides reassurance, helps identify treatable causes and ensures that symptoms requiring further assessment are recognised promptly.

What Are Persistent Headaches?

There is no single definition of a persistent headache, but the term generally describes headaches that:

continue for several consecutive days;
occur repeatedly over weeks or months;
gradually become more frequent;
change in character or severity;
begin interfering with work, sleep or everyday life.

Persistent headaches do not automatically indicate a serious illness.

Many people diagnosed with persistent headaches have common conditions such as tension-type headaches or migraine. Others may have headaches related to lifestyle, medication or another underlying health issue.

The important point is that persistent symptoms should be assessed in the context of your overall health rather than managed indefinitely with repeated over-the-counter pain relief.

Types of Persistent Headaches

Not all headaches are the same. Understanding the pattern of your symptoms often provides valuable clues about the underlying cause.

Type of headache	Typical features	Common management
Tension-type headache	Tight or pressing sensation affecting both sides of the head	Lifestyle advice, identifying triggers, appropriate pain relief where necessary
Migraine	Moderate to severe headache often associated with nausea, sensitivity to light or sound	Individual assessment and migraine-specific management where appropriate
Medication overuse headache	Frequent headaches associated with regular use of pain medication	Medication review under GP supervision
Secondary headache	Headache caused by another underlying condition	Investigation and treatment directed at the underlying cause

Your GP will assess your symptoms carefully because different headache disorders require different management.

Why Persistent Headaches Should Never Be Self-Diagnosed

Many people search online hoping to identify the cause of their headaches.

Although reliable health information can be helpful, headaches are rarely diagnosed based on a single symptom alone.

Two people may describe similar pain but have completely different underlying causes.

Equally, one individual may experience migraine for many years before noticing a change in their symptoms that requires further assessment.

This is why GPs look beyond the headache itself and consider your overall medical history, lifestyle, current medications and associated symptoms before reaching a clinical opinion.

Common Causes of Persistent Headaches

Persistent headaches have many possible causes.

Fortunately, most headaches seen in primary care are not associated with serious neurological disease.

Some of the more common causes include:

Tension-Type Headaches

Tension-type headaches are among the most frequently diagnosed headache disorders.

Symptoms often include:

pressure or tightness across the forehead;
pain affecting both sides of the head;
discomfort extending into the neck or shoulders;
mild to moderate pain rather than severe throbbing.

These headaches are commonly associated with:

stress;
muscle tension;
prolonged desk work;
poor posture;
inadequate sleep.

Although usually not dangerous, they can significantly affect quality of life when they occur frequently.

Migraine

Migraine is a common neurological disorder rather than simply a “bad headache.”

Symptoms vary between individuals but may include:

moderate or severe headache;
nausea;
vomiting;
sensitivity to light;
sensitivity to sound;
visual disturbances;
difficulty concentrating.

Some people experience warning symptoms before the headache develops, while others do not.

A proper diagnosis is important because migraine management differs from other headache disorders.

Medication Overuse Headache

Taking pain-relieving medication frequently over prolonged periods may itself contribute to ongoing headaches in some people.

This does not mean that pain relief should be avoided.

Instead, anyone regularly relying on medication for headaches should discuss their symptoms with a GP to determine whether a medication review may be appropriate.

Lifestyle Factors

Lifestyle plays an important role in headache frequency for many people.

Potential contributing factors include:

dehydration;
poor sleep;
irregular meal patterns;
excessive caffeine intake;
alcohol consumption;
emotional stress;
prolonged screen exposure;
lack of physical activity.

Lifestyle factors rarely explain every persistent headache, but identifying modifiable triggers can form an important part of long-term management.

Eye Strain

People who spend long hours using computers, tablets or mobile devices may experience headaches associated with prolonged visual effort.

Symptoms sometimes occur alongside:

tired eyes;
blurred vision;
difficulty focusing;
neck discomfort.

Where appropriate, your GP may recommend an eye examination to assess whether vision is contributing to your symptoms.

Hormonal Changes

Hormonal fluctuations can influence headaches in some individuals.

Examples include:

menstruation;
pregnancy;
menopause;
changes in hormonal contraception or hormone replacement therapy.

Keeping a headache diary may help identify recurring hormonal patterns.

Sinus Conditions

Inflammation affecting the sinuses may cause facial discomfort around the forehead, eyes or cheeks.

Symptoms may include:

nasal congestion;
facial pressure;
reduced sense of smell;
discomfort when bending forwards.

However, many headaches that people believe are caused by “sinus problems” are actually due to other headache disorders. A clinical assessment helps distinguish between these possibilities.

Less Common Causes

Occasionally, persistent headaches may be associated with:

infections;
inflammatory conditions;
sleep disorders;
certain neurological conditions;
medication side effects;
other underlying medical problems.

For this reason, persistent headaches should always be considered within the wider context of your overall health rather than in isolation.

Looking Beyond the Headache

One of the greatest strengths of a GP consultation is that it considers far more than the pain itself.

During an assessment, your doctor will evaluate:

your age;
previous medical history;
family history;
current medications;
blood pressure;
sleep quality;
stress levels;
occupation;
recent illnesses;
lifestyle habits;
associated symptoms.

This holistic approach helps ensure that any investigations or referrals are based on your individual clinical circumstances rather than on the headache alone.

Common Myths About Persistent Headaches

Myth: Every persistent headache is a brain tumour.

Reality: Fortunately, this is extremely uncommon. Most persistent headaches assessed in primary care have far less serious causes.

Myth: If painkillers help, there is nothing to worry about.

Reality: Temporary relief does not explain why headaches are occurring. Persistent or changing symptoms should still be assessed.

Myth: Stress is always the cause.

Reality: Stress can contribute to headaches, but it should never automatically be assumed to be the only explanation.

Myth: Everyone with headaches needs a brain scan.

Reality: Brain imaging is recommended only when specific clinical features indicate that further investigation is appropriate.

When Should You See a GP About Persistent Headaches?

Most headaches improve without medical treatment and are not a cause for concern. However, persistent headaches should not be ignored if they continue, become more frequent or start affecting your quality of life.

One of the most important things to remember is that a change in your usual headache pattern is often more significant than the intensity of the pain itself.

For example, a headache that gradually becomes more frequent over several weeks may deserve assessment even if it is relatively mild.

Likewise, someone who has experienced migraine for many years but notices a sudden change in their symptoms should seek medical advice rather than assuming it is “just another migraine.”

A GP consultation allows your symptoms to be assessed in the context of your overall health, helping determine whether reassurance, treatment or further investigation is appropriate.

When Should You Book a GP Appointment?

You should consider arranging an appointment if your headaches:

continue for several days without improving;
occur regularly over several weeks or months;
become progressively more frequent;
become more severe than usual;
feel different from headaches you have experienced before;
regularly interfere with work, study or daily activities;
disturb your sleep or wake you during the night;
are present most mornings;
are no longer relieved by simple self-care measures;
occur alongside other symptoms that concern you.

Seeking advice early does not mean that something serious is suspected.

Instead, it allows your GP to identify possible causes, discuss appropriate treatment and decide whether any investigations are clinically necessary.

Red Flag Symptoms: When Should You Call 999?

Although the vast majority of headaches are not medical emergencies, some symptoms require immediate assessment.

Call 999 or attend your nearest Emergency Department immediately if you develop:

a sudden, extremely severe headache that reaches maximum intensity within seconds (“thunderclap headache”);
headache following a significant head injury;
loss of consciousness;
confusion or unusual drowsiness;
seizures;
weakness affecting the face, arm or leg;
difficulty speaking or understanding speech;
sudden loss of vision or persistent double vision;
headache accompanied by fever, neck stiffness and a rash;
headache together with persistent vomiting and reduced consciousness.

These symptoms do not always indicate a serious condition, but they should always be assessed urgently.

What Will a GP Ask During Your Appointment?

Diagnosing persistent headaches begins with a detailed conversation.

Rather than focusing only on the pain, your GP will explore how the headaches fit into your overall health.

You may be asked:

When did the headaches first begin?
How often do they occur?
How long does each episode last?
Where is the pain located?
Is the pain dull, pressing, sharp or throbbing?
Has the headache pattern changed recently?
Do the headaches occur at a particular time of day?
What seems to trigger them?
What makes them better or worse?
Have you noticed nausea, dizziness or visual disturbances?
Are you taking any medication regularly?
Is there a family history of migraine or neurological conditions?

These questions often provide more diagnostic information than the headache itself.

Why Your Medical History Matters

Two patients with similar headaches may have completely different underlying causes.

This is why your GP will also ask about:

previous medical conditions;
recent infections;
current medications;
previous head injuries;
allergies;
hormonal changes;
sleep quality;
stress levels;
occupation;
lifestyle habits.

Understanding the wider clinical picture helps ensure that any investigations are based on evidence rather than assumptions.

Physical Examination

Depending on your symptoms, your GP may perform a physical examination.

This may include:

measuring your blood pressure;
checking your temperature if infection is suspected;
examining your eyes where appropriate;
assessing neck movement;
performing a basic neurological examination;
checking coordination and balance;
reviewing your general health.

In many people, a detailed history together with a normal examination provides enough information to diagnose a common headache disorder without the need for further tests.

Could High Blood Pressure Be Causing Your Headaches?

Blood pressure is routinely measured during many GP consultations.

A common misconception is that headaches are usually caused by high blood pressure.

In reality, most people with high blood pressure do not experience headaches.

However, headaches may occasionally occur when blood pressure is severely elevated, particularly if accompanied by other concerning symptoms.

Measuring blood pressure provides valuable clinical information and helps ensure that an important risk factor is not overlooked.

Are Blood Tests Ever Needed?

Many patients expect blood tests to be part of every headache assessment.

In reality, this is not always necessary.

Blood tests are recommended only when your symptoms, examination findings or medical history suggest they may help identify an underlying condition.

Depending on your individual circumstances, your GP may recommend tests to assess:

iron deficiency or anaemia;
thyroid function;
vitamin deficiencies such as vitamin B12 or vitamin D;
markers of inflammation;
blood glucose levels;
kidney function;
liver function;
electrolyte balance.

These investigations do not diagnose headaches directly.

Instead, they help identify medical conditions that may contribute to persistent symptoms.

At Evergreen Richmond, GP-led blood testing ensures that investigations are requested only when clinically appropriate and interpreted within the context of your overall health rather than in isolation.

Do You Need a Brain Scan?

One of the biggest concerns for people experiencing persistent headaches is whether they need a CT or MRI scan.

Fortunately, most people do not.

Current clinical guidance recommends brain imaging only when specific clinical features indicate that further investigation is appropriate.

Your GP will consider:

your age;
neurological examination findings;
changes in your headache pattern;
associated symptoms;
previous medical history;
whether any “red flag” features are present.

Avoiding unnecessary scans is an important part of evidence-based medicine.

Investigations should only be performed when they are likely to influence diagnosis or treatment.

If imaging is appropriate, your GP will explain why it has been recommended and arrange referral accordingly.

When Might You Be Referred to a Specialist?

Most persistent headaches can be assessed and managed within primary care.

However, referral may be appropriate if:

the diagnosis remains uncertain;
symptoms persist despite appropriate treatment;
neurological symptoms develop;
further specialist investigation is required;
another underlying condition is suspected.

Referral does not necessarily mean a serious condition has been identified.

Instead, it ensures that patients receive the most appropriate expertise when additional assessment is clinically indicated.

If you are unsure whether you should see a GP or a specialist first, our guide GP or Specialist: Which Doctor Should You See First? explains how referral decisions are made and why primary care is often the best place to begin.

Keeping a Headache Diary

Before your appointment, keeping a headache diary can provide valuable information.

Consider recording:

when each headache begins;
how long it lasts;
where the pain is located;
pain severity;
associated symptoms;
medication taken;
possible triggers;
sleep quality;
menstrual cycle (where relevant);
whether the headache affected work or daily activities.

Even a diary covering two or three weeks can help identify patterns that may not otherwise be obvious.

What Happens After Your GP Appointment?

At the end of your consultation, your GP will discuss the most appropriate next steps.

Depending on your individual assessment, this may include:

reassurance where no concerning features are identified;
advice on lifestyle changes;
headache management strategies;
medication review;
arranging blood tests if clinically indicated;
monitoring symptoms over time;
referral for further investigation where appropriate.

Every patient is different.

For this reason, treatment plans are tailored to the individual’s symptoms, medical history and examination findings rather than following a one-size-fits-all approach.

Why Seeing a GP First Makes Sense

Persistent headaches can have many different causes.

Starting with a GP allows your symptoms to be assessed comprehensively while avoiding unnecessary investigations or referrals.

A GP considers not only the headache itself but also your general health, current medications, lifestyle, risk factors and any associated symptoms before deciding on the most appropriate management plan.

This holistic approach often leads to faster diagnosis, more appropriate treatment and greater reassurance.

How Are Persistent Headaches Treated?

There is no single treatment that works for every type of persistent headache.

The most appropriate management depends on identifying the underlying cause rather than simply relieving the pain.

Following your assessment, your GP will discuss an individual management plan based on your symptoms, medical history, examination findings and any investigations that may have been performed.

Depending on the diagnosis, treatment may include:

lifestyle advice;
identifying and reducing headache triggers;
reviewing current medications;
migraine-specific treatment where appropriate;
physiotherapy if muscle tension is contributing to symptoms;
treatment of an underlying medical condition;
monitoring symptoms over time;
referral for specialist assessment if clinically indicated.

Many people experience significant improvement once the underlying cause has been identified and managed appropriately.

Can Persistent Headaches Be Prevented?

Although not every headache can be prevented, adopting healthy lifestyle habits may help reduce the frequency of headaches in many people.

Your GP may discuss strategies such as:

maintaining good hydration;
following a regular sleep routine;
eating balanced meals without regularly skipping breakfast or lunch;
limiting excessive alcohol intake;
keeping caffeine intake consistent;
taking regular breaks from prolonged screen use;
improving posture when working at a desk;
remaining physically active;
managing stress using techniques that suit your lifestyle.

Prevention is rarely based on one single change. Instead, it often involves identifying personal triggers and making sustainable long-term adjustments.

Common Mistakes People Make

One reason headaches sometimes become persistent is that people unknowingly adopt habits that make symptoms more difficult to control.

For example, some of the most common mistakes include:

Ignoring symptoms for several months

Many people hope headaches will simply disappear. While this is often true, persistent or changing headaches deserve proper assessment.

Taking painkillers too frequently

Regular use of pain-relieving medication without medical advice may contribute to medication overuse headache in some individuals.

Assuming stress is always responsible

Stress is a common trigger, but it should never automatically be considered the only explanation.

Searching for a diagnosis online

Online information can be helpful, but headaches require assessment within the context of your overall health, medical history and examination findings.

Expecting a brain scan at every appointment

Most people with persistent headaches do not require CT or MRI imaging. Your GP will recommend investigations only when clinically appropriate.

Why Continuity of Care Matters

Persistent headaches are often easier to assess over time than during a single consultation.

Whenever possible, seeing the same GP allows subtle changes to be recognised more easily and enables your treatment plan to be adjusted if necessary.

Continuity of care may help your doctor:

monitor headache frequency;
review treatment effectiveness;
identify new symptoms early;
decide whether additional investigations are required;
determine whether referral to a specialist is appropriate.

This ongoing relationship often provides reassurance while supporting more personalised healthcare.

Looking at Your Health as a Whole

Persistent headaches sometimes occur alongside other symptoms that may initially appear unrelated.

For example:

ongoing tiredness;
poor sleep;
nutritional deficiencies;
hormonal changes;
high levels of stress;
chronic health conditions.

Therefore, rather than treating one symptom in isolation, your GP considers your overall health.

Where appropriate, a broader assessment may identify underlying factors that contribute not only to headaches but also to your general wellbeing.

If appropriate for your individual circumstances, a comprehensive Health Screening may provide a wider overview of your health and identify risk factors before symptoms develop further.
