Acute Pain vs Chronic Pain

Acute pain is a short-term alarm that protects you while the body heals. It is linked to an injury, surgery or illness, and settles as the body recovers.

Chronic pain continues beyond about three months and can behave differently – often because the nervous system has become more sensitive (the alarm has been “turned up”), not because damage is getting worse.
