What Should You Do?
If you develop a sudden, severe headache unlike any you’ve experienced before—especially if it is accompanied by vomiting, confusion, weakness, vision changes, or loss of consciousness—seek emergency medical care immediately.
If you have persistent neurological symptoms that are new or unusual, arrange prompt evaluation by a healthcare professional. Early diagnosis allows doctors to determine the cause and recommend appropriate treatment.
