What should you know about PMR headache?

Record where the pain is, how it feels, when it started, how long episodes last and what makes it better or worse. A blocked or runny nose can accompany allergic rhinitis, a cold or chronic sinusitis; fever and body symptoms can occur with COVID-19 or dengue fever. Heat exhaustion and dehydration may bring headache with thirst, dizziness or weakness. Stress and anxious muscle tension can also contribute. These associations are clues, not proof of the cause.

Rest somewhere cool and quiet, drink fluids regularly and eat if you have missed meals. Limit alcohol and take only pain medicine that is suitable for you and used according to its label or a clinician's advice. Keep a headache diary, including sleep, screen time, heat exposure, congestion, medicines and menstrual timing when relevant. Arrange an appointment for new, recurrent or disruptive headaches so the pattern and neurological symptoms can be assessed.

Call emergency services for a sudden severe headache, new weakness or numbness, trouble speaking, seizure, fainting, confusion, severe neck stiffness or a headache after a significant head injury. Seek same-day care for headache with persistent vomiting, a high fever, vision loss, a new rash or worsening symptoms in hot conditions.
