I'm sorry to hear that you've been experiencing a severe headache for a week. Persistent severe headaches can be concerning and may require thorough evaluation to determine the underlying cause.

Here are some important points to consider:

• Duration and severity: A headache lasting a week, especially if severe, should be assessed by a doctor to rule out serious conditions.
• Possible causes: These can range from migraines, tension headaches, medication overuse, infections, or other neurological issues.
• Medication caution: There is a medication called Napra D 250 Tablet, which contains Naproxen (a pain reliever) and Domperidone (to control nausea), used for migraine headaches. However, this should only be taken under medical supervision, especially if you have other health conditions.
• When to seek urgent care: If you experience additional symptoms such as vision changes, weakness, confusion, fever, neck stiffness, or sudden worsening of headache, please seek emergency medical attention immediately.

Recommendation: Please consult a neurologist or your primary care doctor promptly to evaluate your headache, discuss your symptoms in detail, and receive appropriate investigations and treatment. Avoid self-medicating without professional guidance. If your symptoms worsen or new concerning signs appear, do not hesitate to visit an emergency facility.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
