What does it mean when the back of your head and skull hurts extremely?

Extreme pain in the back of your head and skull can indicate several issues, such as tension headaches, migraines, or even cervical spine problems. It could also be a sign of increased intracranial pressure or a more serious condition like a concussion or an underlying neurological disorder. If the pain is severe, persistent, or accompanied by other symptoms like nausea, vision changes, or confusion, it's important to seek medical attention promptly. Always consult a healthcare professional for an accurate diagnosis and appropriate treatment.
