How do you know if your headache is serious?

It's important to seek medical attention if you experience any of the following symptoms along with a headache:

- Sudden onset of a severe headache unlike any you've had before (thunderclap headache)

- Headache accompanied by fever, stiff neck, nausea, or vomiting

- Headache that worsens progressively or doesn't improve with over-the-counter pain medication

- Headache accompanied by neurological symptoms such as vision changes, weakness, numbness, or difficulty speaking

- Headache that wakes you up from sleep or is present upon waking

- Headache that is associated with a head injury or trauma

- Chronic headaches that are increasingly frequent or severe

If you have any concerns about the severity of your headache or if it is accompanied by any of these symptoms, it's best to consult a healthcare professional for proper evaluation and diagnosis.
