Hypertension and migraine

Migraine can cause throbbing head pain, nausea, light sensitivity or visual symptoms. Pain and anxiety may temporarily raise a blood pressure reading. Conversely, very severe hypertension can harm the brain and may present with headache, but this is an emergency pattern rather than an explanation for ordinary recurrent migraine.

Track when pain starts, where it is felt, associated symptoms, medicines taken and blood pressure readings made after resting. This helps a clinician distinguish a familiar migraine pattern from a new problem. Some painkillers and decongestants can affect blood pressure, so mention all products you use.

Rest in a quiet, dim room if this resembles your diagnosed migraine, drink fluids if you can, and measure blood pressure only after sitting quietly. Follow your agreed migraine and blood pressure treatment plans. Do not take extra blood pressure tablets to treat a headache unless a clinician has specifically instructed you.

Book a review for a first severe headache, a changed pattern, frequent attacks, or repeated high readings. Keep a diary with sleep, meals, stress, menstrual timing and medicines because triggers and treatment effects can become clearer over time.

Call emergency services for a sudden explosive headache, new weakness or numbness, facial drooping, difficulty speaking, confusion, seizure, fainting, severe breathlessness, chest pain or sudden loss of vision. These signs may indicate stroke or another acute emergency.

Seek urgent assessment for a severe headache with fever and a stiff neck, after a head injury, during pregnancy, or when it is unlike your usual migraine. Do not drive yourself if neurological symptoms are present.

Ask whether your symptoms fit migraine, how to measure during an attack, which pain medicines suit your blood pressure, and what reading or symptom should trigger urgent help. Discuss medication interactions before using cold remedies or frequent painkillers.
