Cluster headache at the back of the head: what should you know?

Cluster headache typically centres around one eye or the temple, though pain can radiate toward the scalp, neck, or back of the head. The associated signs matter: tearing or redness of one eye, nasal blockage or discharge on the same side, and restlessness during an attack can support the pattern. Back-of-head pain can also arise from neck structures, migraine, nerve irritation, infection, or other causes. Use the Headache and Facial Pain and Pressure pages to describe where pain begins and where it travels.

Write down the starting point, direction of spread, side, intensity, duration, movement or neck effects, eye and nose changes, fever, injury, and medicines. Avoid assuming that a familiar diagnosis explains a new location. Arrange a GP Consultation for recurrent or severe episodes, particularly if the pain is unlike previous headaches. A physical and neurological assessment can guide whether further testing or specialist input is needed.

Seek emergency help for a sudden severe headache, weakness, numbness, speech trouble, confusion, fainting, seizure, fever with a stiff neck, or persistent vision change. Prompt review is needed after head or neck injury, when pain is progressively worsening, or when it is triggered by exertion, coughing, or straining.

Does the location and pattern fit cluster headache? Could the neck or nerves be contributing? Which examination findings would change the plan? What can I use during an attack, and what symptoms mean I should attend emergency care?
