When to Speak to a Healthcare Professional About Headaches

Urgent information

NHS guidance advises calling 999 or going to an emergency department if a headache comes on suddenly and is extremely painful, or if a headache occurs with any of the following: difficulty speaking or remembering things, loss of vision, drowsiness or confusion, a very high temperature with symptoms of meningitis such as a stiff neck or a rash, weakness or numbness on one side or in the face, a seizure, or a head injury. NHS guidance also advises asking for an urgent GP appointment or calling 111 if a headache keeps coming back, is not eased by ordinary painkillers, is worse when lying down or bending over, comes with jaw pain when eating, or comes with blurred or double vision. Follow the NHS advice itself rather than this summary.

New or changing headaches

A headache that is new for you, or that has changed in character, location, timing or intensity, is worth discussing with a GP. That is true even when it is mild. A change in a familiar pattern is useful clinical information, and it is easier to describe soon after it happens than months later.

Headaches that are becoming more frequent

Frequency matters as much as severity. Make an appointment if attacks are coming more often than they used to, or if you are relying on painkillers regularly. NICE guidance highlights medication overuse headache, where frequent use of acute painkillers can itself contribute to more frequent headaches, as something to consider and discuss with a clinician.

• 01Headaches more often than they used to be
• 02Acute pain relief used on several days most weeks
• 03Ordinary painkillers no longer helping as they did
• 04A pattern that has shifted without an obvious reason

Headaches affecting daily life

Impact is a legitimate reason to seek help on its own. If headaches are causing missed work, cancelled plans, difficulty caring for others, or disturbed sleep, that is worth an appointment even if you have been managing for years.

Keeping a record before an appointment

Appointments are short. A few weeks of notes make them far more productive, and NICE guidance supports using a headache diary to help assess and review headache disorders.

• 01The date and time each headache started and stopped
• 02Where the pain was, and what it felt like
• 03Other symptoms, such as nausea or sensitivity to light and sound
• 04What you took, how much, and whether it helped
• 05What you could not do that day
• 06Anything you noticed beforehand, including sleep and meals

Information to share with a GP

Bring the practical details rather than a theory. It saves time and helps avoid a second appointment for the same question.

• 01How long you have had headaches and how they have changed
• 02How many days a month you are affected
• 03All medicines you use, including over the counter ones and supplements
• 04Any other health conditions, and family history of headache
• 05Whether you are pregnant, breastfeeding, or trying to conceive
• 06What you most want to change as a result of the appointment

When urgent assessment may be needed

The urgent information section above summarises the NHS list. It is a summary and not a complete account, and no article can rule anything out for you. If something about a headache feels different from your usual pattern and you are unsure what to do, contacting 111 is a reasonable step rather than an overreaction.
