Orthostatic headache: what you should know

Posture-sensitive pain can occur with dehydration, heat exposure, or an illness causing congestion and facial pressure. Allergic rhinitis, chronic sinusitis, and a common cold may produce pressure around the nose and face, but a headache that reliably changes with position needs a broader assessment. Fever, recent infection, neck symptoms, or a recent procedure may change how urgently it should be reviewed.

A clinician will ask how quickly the pain starts after standing, how it behaves when lying down, where it is located, and whether you have nausea, visual symptoms, weakness, or fever. They may check your neurological function and vital signs, then decide whether further investigation is needed.

Rest in a comfortable position, rise slowly, and drink fluids if you can do so safely. Avoid overheating and note the timing, posture, severity, associated symptoms, recent illness, and medicines taken. Do not repeatedly test the pain by standing for long periods, and do not rely on pain medicine to explain away a persistent positional pattern.

Arrange a medical review when the headache is new, recurrent, worsening, or limiting normal activity. If you have fever or respiratory symptoms, mention them; COVID-19 and other infections can change the assessment. Dehydration and heat exhaustion may also need attention when headache follows fluid loss or prolonged heat.

Seek emergency care for a sudden severe headache, new weakness or numbness, trouble speaking, confusion, seizure, fainting, severe neck stiffness, repeated vomiting, or major vision change. Get prompt medical advice for a new headache after a head injury, during pregnancy, with persistent fever, or with a pattern that consistently improves only when lying down. Do not wait for the symptom to become unbearable.

Ask what features make the headache positional, whether your examination suggests infection or another cause, and whether tests are needed. Ask which pain-relief options are suitable for you, how much activity is sensible, and which changes should trigger urgent care.
