Headache, migraine and dizziness resources
Why is my headache on one side, or why does it switch sides?

Quick answer
Migraine can affect one side or both sides of the head, and its location can change. The side alone cannot identify the cause or prove that your neck is responsible. A new, severe or changing pattern needs assessment.
Which details matter beyond the side?
Describe the quality and duration of pain, associated nausea or sensory sensitivity, and how often it occurs. Note eye watering, nasal symptoms, visual changes or pain around the jaw. These details give your clinician more information than a location alone.
The original MHS post asked why pain can switch sides. If that is your concern, record whether it happens within one attack or between attacks, and whether this is familiar or a recent change.
Does side-switching prove a neck cause?
No. Neck symptoms can be relevant to assessment, but a diagram of referred pain or a change in location cannot establish the diagnosis. A clinician should consider the headache history and examination together.
Tell your practitioner about movements or positions that change familiar pain without repeatedly provoking it yourself. Also include attacks with no neck discomfort so the history is complete.
When should I seek help?
Arrange medical advice if the pattern is new, progressively worse or disrupting ordinary activity. Sudden severe headache, loss of vision, new weakness or speech problems requires urgent help, even if you have had migraine before.
MHS can assess your headache presentation and relevant physical symptoms alongside your existing medical care. Bring a short diary and previous advice, and ask what the findings suggest rather than expecting pain location to supply the answer.
