In short
Migraine is a distinct neurological condition with recognizable patterns and triggers, not simply an unusually severe headache.
Emergency if: A headache that starts suddenly and is extremely painful, or any headache with weakness or numbness on one side of the body or face, difficulty speaking or remembering, loss of vision or double vision, drowsiness or confusion, a seizure, or a very high fever with a stiff neck or rash: call emergency services now.

What Makes Migraine Different
A tension headache typically produces a dull, pressing ache on both sides of the head. Migraine tends to behave differently: it often throbs, concentrates on one side, and comes bundled with nausea, sensitivity to light or sound, and sometimes visual disturbances called aura that arrive before the pain itself.
Migraine also tends to run in recognizable episodes, with a build-up phase, the headache itself, and a recovery period afterward that can leave someone feeling drained for a day or more. This episodic, multi-phase pattern is one of the clearest ways clinicians distinguish it from other headache types.
02
Common Triggers
Triggers vary widely between individuals, which is part of why migraine can be hard to predict. Commonly reported ones include disrupted sleep, skipped meals, dehydration, certain foods or alcohol, hormonal shifts, strong smells, and stress, or even the letdown after a stressful period ends.
Weather changes and bright or flickering light are also frequently mentioned. Because triggers are individual, many people find it useful to track headaches alongside sleep, meals, and stress for a few weeks to spot their own patterns rather than relying on generic trigger lists.
03
The Treatment Landscape
Treatment generally falls into two categories: options taken during an attack to stop it, and preventive options taken regularly to reduce how often attacks happen. The right mix depends on how frequent and disabling the migraines are, and it is decided with a clinician rather than through self-experimentation.
Non-drug approaches, including regular sleep, consistent meals, and stress management, are often recommended alongside any medical treatment, since they can reduce attack frequency for many people even when used on their own.

Living With Migraine
Because migraine is a chronic tendency rather than a one-time illness, many people benefit from an ongoing relationship with a healthcare provider to adjust strategies over time as patterns change. A change in your usual headache pattern deserves a medical review. A headache that starts suddenly and is extremely painful, or one with weakness, numbness, speech or vision problems, confusion or a seizure, is an emergency: call emergency services now.
When to act
Emergency — act now
A headache that starts suddenly and is extremely painful, or any headache with weakness or numbness on one side of the body or face, difficulty speaking or remembering, loss of vision or double vision, drowsiness or confusion, a seizure, or a very high fever with a stiff neck or rash: call emergency services now.
Same-day — call promptly
A migraine attack that has lasted longer than 72 hours, or aura that lasts longer than an hour: see a doctor today. If you are pregnant or gave birth recently and have a bad headache, contact your maternity unit today.
Routine — see a doctor
Attacks more than once a week, attacks that are getting worse, lasting longer or are hard to control, or attacks around your period: book an appointment to talk about prevention.
