Recurring Headaches
Symptoms, Causes & Treatment
Recurring headaches affect millions of people in the UK. Most are benign — migraine or tension-type headache — but some require urgent assessment to exclude dangerous causes. Accurate diagnosis is the key to effective treatment.
What are Recurring Headaches?
Recurring headaches encompass migraine (affecting 1 in 7 people), tension-type headache (the most common type), cluster headache, medication overuse headache, and secondary headaches from underlying conditions. The type of headache determines both the treatment approach and the urgency of assessment.
Symptoms of Recurring Headaches
Headache character, location, duration, associated features, and timing all help identify the specific headache type.
Recurring headache on 15 or more days per month · Throbbing or pulsating pain, often one-sided · Nausea or vomiting with headache · Sensitivity to light (photophobia) and sound (phonophobia) · Tension-type: band-like pressure around the head · Headache worsening with physical activity
Sudden severe ‘thunderclap’ headache (worst of your life) — possible subarachnoid haemorrhage, call 999 · New headache with fever and neck stiffness · Headache with neurological deficit (weakness, vision loss, speech difficulty) · Progressive worsening headache over days or weeks · New headache over age 50
Thunderclap headache, headache with fever and stiff neck, neurological symptoms (weakness, vision loss, speech difficulty), or new headache over age 50 — seek emergency care immediately.
What Causes Recurring Headaches?
Recurring headaches arise from multiple mechanisms. Accurate classification guides effective treatment.
Migraine is caused by cortical spreading depression and trigeminovascular activation. Triggers include hormonal changes, stress, sleep disruption, dehydration, alcohol, and certain foods. It has a strong genetic component and affects 1 in 7 people in the UK.
Tension-type headache (TTH) is the most common headache disorder, caused by pericranial muscle tenderness and central sensitisation. Chronic TTH (15+ days/month) is often associated with medication overuse, anxiety, and poor sleep.
Medication overuse headache (MOH) develops when analgesics or triptans are used on 10–15 or more days per month. The brain becomes sensitised, causing daily or near-daily headaches. Treatment requires withdrawal of the overused medication.
Cluster headache causes severe unilateral periorbital pain with ipsilateral autonomic features (ptosis, lacrimation, nasal congestion) occurring in clusters lasting weeks to months. It is more common in men and is one of the most severe pain syndromes known.
Cervicogenic headache arises from neck structures and is referred to the head. It is worsened by neck movement and associated with tender cervical muscles and reduced neck range of motion. Physiotherapy is the cornerstone of management.
Secondary headaches result from identifiable causes including hypertension, meningitis, subarachnoid haemorrhage, space-occupying lesions, and temporal arteritis. All new headaches in adults over 50, or those with red flag features, require investigation.
Key Risk Factors
Diagnosing Recurring Headaches
Diagnosis is primarily clinical, based on headache history and diary. Investigations are only needed when red flag features are present.
Treatment for Recurring Headaches
Treatment is tailored to headache type. Acute treatment targets individual attacks; preventive treatment reduces frequency and severity.
Supportive Measures
Rest in a quiet, dark room during a migraine. Apply cold or warm compress to the head or neck. Stay hydrated. Avoid known triggers. Use a headache diary to track patterns and identify what helps most.
Chronic & Refractory Headache
Chronic migraine (15+ headache days/month) and medication overuse headache require specialist referral, preventive treatment, and/or CGRP monoclonal antibody therapy. Withdrawal of overused analgesics is an essential step, even though it temporarily worsens headaches.
When to Seek Help
Thunderclap headache (worst of your life) · Headache with fever, neck stiffness, or rash · Headache with neurological deficit · New headache over age 50 — call 999 or go to A&E immediately.
Book a GP appointment if headaches occur 4 or more days per month, are not responding to over-the-counter treatment, or are significantly affecting daily life. An online consultation is a convenient first step.
Preventing Recurring Headaches
Most recurring headaches can be significantly reduced through lifestyle modification and preventive treatment.
Keep a headache diary for 4–8 weeks recording frequency, severity, triggers, and medications used. This identifies patterns, detects MOH, and guides treatment. Apps such as Migraine Buddy make diary-keeping easy.
Stay well hydrated throughout the day. Skipping meals is a common migraine trigger. Eat regular small meals, avoid skipping breakfast, and maintain stable blood glucose levels.
Sleep at the same time each night and wake at the same time. Both too little and too much sleep trigger migraines. Aim for 7–9 hours. Avoid weekend lie-ins beyond one hour of usual wake time.
Limit analgesic use to no more than 10–15 days per month to prevent medication overuse headache. If you need pain relief this frequently, review preventive treatment options with your GP.
Regular aerobic exercise (3–5 sessions per week) reduces migraine frequency. Start slowly — sudden intense exercise can trigger migraines. Combine exercise with stress management for best results.
Identify and minimise personal triggers. Common triggers include red wine, aged cheese, strong smells, bright lights, screen time, hormonal changes, and high stress. Not all triggers can be avoided, but awareness helps.
Getting Treatment
A GP can diagnose and treat migraine, tension headache, and medication overuse headache. An online GP consultation is an effective first step. Red flag headaches require same-day emergency care.

Recurring Headaches — Frequently Asked Questions
Headaches lasting 15 or more days per month for more than 3 months are classified as chronic daily headache. This often includes chronic migraine or chronic tension-type headache, frequently complicated by medication overuse. A GP can review treatment and consider preventive therapy or specialist referral.
A thunderclap headache — sudden severe headache reaching maximum intensity in seconds — requires emergency assessment. Call 999 or go to A&E immediately. It may indicate subarachnoid haemorrhage, which is life-threatening but treatable if caught early.
Yes. Taking analgesics (paracetamol, ibuprofen, triptans) on 10 or more days per month can cause medication overuse headache — a cycle of daily or near-daily headaches. Treatment requires stopping the overused medication, which initially worsens headaches before improving.
Preventive treatment is indicated if you have 4 or more migraine days per month, or if attacks significantly impact quality of life. Options include propranolol, topiramate, amitriptyline, and — for more severe cases — CGRP monoclonal antibodies.
Yes. Migraine is closely linked to hormonal changes. Many women experience migraines before or during menstruation (menstrual migraine), and migraine often improves in pregnancy. The combined oral contraceptive can worsen migraine with aura and is contraindicated in this group.
Cluster headaches are extremely severe attacks of one-sided pain around the eye, with ipsilateral eye watering, nasal congestion, and ptosis. They occur in clusters lasting weeks to months, multiple times daily. They are not migraines — treatment is different and includes high-flow oxygen and sumatriptan injection.
Triptans should not be used if you have cardiovascular disease, uncontrolled hypertension, or a history of stroke or TIA. They are also best avoided in children under 12 unless prescribed by a specialist. Overuse should be avoided to prevent medication overuse headache.
A GP can diagnose and manage most headache disorders including migraine, tension-type headache, and medication overuse headache. An online GP consultation is a convenient first step. Red flag headaches (thunderclap, with neurological deficit, or progressive) require same-day emergency assessment.
