What should you know about hot pack for headache?

Gentle warmth over the neck, shoulders, or forehead can feel soothing when muscle tension contributes to head pain. Some people prefer a cool pack, especially when heat feels unpleasant or the head pain has migraine-like features. Headache can also accompany a cold, allergic rhinitis, sinus inflammation, dehydration, anxiety, or a viral illness, so a hot pack may provide comfort without addressing the underlying problem.

Use a comfortably warm, not scalding, pack wrapped in cloth and place it on the tense area while awake. Check your skin regularly and stop if it becomes very red, numb, or painful. Rest in a quiet space, drink fluids if you may be dehydrated, and avoid pressing directly on the eyes. Follow medicine instructions carefully and ask a pharmacist if you take other medicines or have a condition affecting sensation or circulation.

Get emergency help for a sudden severe headache, new weakness or numbness, trouble speaking, confusion, fainting, seizure, stiff neck with fever, or new vision loss. Seek medical advice for a headache after a head injury, repeated vomiting, persistent fever, or a pattern that is new, worsening, or disrupting daily activities.

Does the pattern suggest tension, migraine, sinus disease, infection, or another cause? Should I use heat or cooling? Which symptoms mean I should attend urgent care, and how can I prevent these headaches from recurring?
