I'm sorry to hear that you're experiencing a severe headache. Headaches can have many causes, ranging from tension or migraine to more serious conditions. Since your headache is severe and has lasted since this morning, it is important to take it seriously.

Here are some steps you can consider:

• Rest in a quiet, dark room to help reduce headache intensity.
• Stay hydrated by drinking water.
• If you have a medication like Napra-D 500 Tablet (which contains naproxen and domperidone) prescribed for migraine or pain relief, you may take it as directed by your doctor. However, do not self-medicate without professional advice.
• Avoid any triggers you may know, such as bright lights, loud noises, or certain foods.

Because severe headaches can sometimes indicate serious conditions, especially if accompanied by symptoms like vision changes, weakness, confusion, fever, neck stiffness, or vomiting, it is important to seek prompt evaluation.

Please contact a neurologist or visit an emergency department immediately if:

• The headache is the worst you have ever had.
• You experience sudden onset of headache.
• You have neurological symptoms like weakness, numbness, difficulty speaking, or vision problems.
• You have a fever or neck stiffness.
