Six Headache Patterns and When to Seek Urgent Help
Headaches are common and most are not caused by serious disease. Their onset, duration, accompanying symptoms and changes from your usual pattern help clinicians decide whether evaluation is needed.
Emergency warning: Seek emergency care for a sudden extremely severe headache, or a headache with new weakness, confusion, difficulty speaking, seizures, substantial vision loss, or fever and a stiff neck.
1. Tension-type headache
Often feels like pressing or tightening on both sides of the head, typically mild to moderate. Regular sleep, meals, hydration and stress management may help. Frequent headaches warrant medical review.
2. Migraine
Migraine is a neurological condition that can involve moderate to severe pain, nausea, and sensitivity to light or sound. Some people experience temporary aura symptoms. New weakness or speech changes must not automatically be attributed to migraine.
3. Cluster headache
Typically causes very severe pain around one eye, sometimes with tearing, a red eye, nasal symptoms or restlessness on the same side. Suspected cluster headache needs clinical diagnosis and targeted treatment.
4. Headache with sinus symptoms
Facial pressure can occur with respiratory infections, but many headaches described as sinus headaches are migraines. Facial pressure alone does not establish bacterial sinusitis or a need for antibiotics.
5. Exercise-, cough- or strain-related headache
Some headaches are triggered by exertion, coughing or straining. A new headache of this type warrants assessment, especially if sudden or unusually intense.
6. Thunderclap headache
A thunderclap headache reaches extreme intensity very quickly, often within seconds to minutes. It may indicate bleeding around the brain or another serious problem. Seek immediate emergency evaluation.
Important warning signs: injury, age and pregnancy
- Headache after a head injury: Seek emergency assessment if a headache follows a significant head injury, particularly if it is worsening or accompanied by vomiting, confusion, drowsiness or neurologic changes. Even with less severe injury, a new headache after a recent blow to the head warrants clinical advice.
- New headache after age 50: A new or substantially different headache in someone over 50 should be assessed promptly, especially with scalp tenderness, jaw pain while chewing or visual symptoms. These can sometimes signal giant cell arteritis, which needs urgent assessment to protect vision.
- Severe or persistent headache during pregnancy or after childbirth: Contact maternity or emergency services urgently, especially if the headache is new, severe, does not go away, or occurs with visual changes, upper abdominal pain, swelling or high blood pressure. Preeclampsia can develop after 20 weeks of pregnancy and during the weeks following delivery. Do not assume a postpartum headache is simply due to fatigue.
Other reasons to seek help
Seek prompt medical advice for headaches that are worsening, becoming more frequent, or significantly different from your usual headaches. A headache diary can help document duration, severity, triggers, symptoms and medicines used. Frequent painkiller use can contribute to medication-overuse headache.
