Learn why pain can outlast tissue healing, how sensitivity and context shape protection, and why persistent pain still deserves careful assessment.
What you’ll learn
- When Protection Outlasts the InjuryDistinguish pain from a direct tissue-damage meter and explain why healing does not guarantee immediate pain resolution.Pain is real protection produced by a nervous system whose relationship with tissue status can change over time.
- How Sensitivity Can RiseExplain peripheral and central sensitization without turning either term into a universal diagnosis.Inflammation and altered processing can increase responsiveness at several levels of the pain system.
- The Brain Predicts ThreatDescribe how prediction, attention, learning, and graded evidence can shape pain after an injury.Past threat can bias protection toward danger, while tolerable safe action can help update the model.
- Why Context MattersUse a biopsychosocial model to connect stress, sleep, attention, social safety, and pain without assigning blame.Pain processing changes with the body's biological state and the person's psychological and social context.
- What Helps the System UpdateIdentify the need for reassessment, red flags, individualized treatment, and function-centered rehabilitation.Persistent pain deserves both medical care and a practical plan for safer activity, participation, and quality of life.
Questions this course answers
Which statement best distinguishes pain from tissue damage?
Pain can be influenced by many biological, psychological, and social factors, so it does not map one-to-one onto current tissue damage.
Why can pain remain after tissue healing?
The relationship between tissue status and pain can change over time without making the pain imaginary.
Match each level with its role.
Persistent pain is best understood as interaction across levels, not as one damaged location.
What is the careful claim about central sensitization?
Central sensitization can be relevant, but current reviews caution against treating it as a single explanation for all chronic pain.
Put this prediction-and-learning account in a sensible order.
Learning can generalize protection, and rehabilitation can provide new evidence without arguing that pain is voluntary.
Why might a previously painful movement still hurt after healing?
Prediction is a normal part of perception; it does not mean the experience is fake.
