Hi-
Immediate care should be sought if the headache is extremely severe, or the worst headache of the person's life. Additionally, care should be sought if there are symptoms such as:
* Slurred speech,
* Numbness,
* Blurry vision,
* Difficulty walking or
* Prominent forehead veins.
Any other unusual symptoms along with the headache (e.g., projectile vomiting) warrants immediate care as well.
Sincerely,
Emily
