About
A headache is pain in the head or face that is often described as a pressure that’s throbbing, constant, sharp or dull. Headaches can differ greatly regarding pain type, severity, location and frequency. While most headaches are not dangerous, certain types can be a sign of a more serious condition.
Types
- Primary – Primary headaches are caused by dysfunction or over-activity of pain-sensitive features in the head and not by an underlying medical condition.
- Secondary – Secondary headaches are caused by an underlying medical condition and are considered a symptom of that condition
