Headache in a Patient With New Visual Symptoms
A 29-year-old woman presents with a 3-week history of daily headaches. She describes a pressure-like band around the head, worse in the afternoon, with associated neck tightness. In the past 5 days she has noticed transient visual obscurations when standing quickly and 'flashing' in the periphery. She takes a combined oral contraceptive and has a body mass index of 33. She has no fever, no focal weakness, and no speech disturbance. Neurologic screening shows symmetric reflexes and intact cranial nerves. She has been told by a friend that 'cervicogenic headaches respond well to neck manipulation' and wants treatment today.
1. Identify the features that require further workup before any cervical manipulation, and explain your reasoning.
Read the worked answer
Several features do not fit a simple cervicogenic or tension-type headache:
- Transient visual obscurations on standing can reflect raised intracranial pressure or transient cerebral hypoperfusion; they warrant funduscopy and consideration of papilledema.
- New peripheral flashing suggests a visual aura or retinal process and requires ophthalmic assessment.
- Combined oral contraceptive use with obesity increases venous thromboembolism and cerebral venous sinus thrombosis risk.
- Daily headache of recent onset with a changing pattern is a red flag for secondary headache.
Cervical manipulation is deferred until secondary causes are excluded. The appropriate next steps are a full headache examination including funduscopy and blood pressure, and referral for further evaluation (neuroimaging and ophthalmologic assessment as indicated). Document the red flags and the rationale for deferral.
2. How would you explain the decision to the patient and structure interim care?

Explain in plain language: her headache pattern includes features that are not typical of neck-related headache, and some of them can indicate conditions that need to be checked before hands-on treatment. Emphasize that deferral is a safety step, not a judgment that her pain is not real.
Interim care:
- Avoid cervical thrust manipulation until evaluation is complete.
- Comfort measures - gentle soft-tissue work to the upper back and shoulders only if non-provocative, heat, sleep and hydration guidance, and a headache diary.
- Clear return precautions - sudden severe headache, visual loss, weakness, confusion, or vomiting require urgent care.
- Coordination - communicate with her primary clinician about the referral and the reason for deferral.
Reassess after evaluation; if secondary causes are excluded and examination supports a cervicogenic component, a graded manual therapy plan can be considered with informed consent.
