What Is Acute Pain?
Acute pain is pain that comes on suddenly, usually as a result of an injury, strain, or tissue irritation. An example of this may include pain following immediately after rolling your ankle or pain following surgery.
Acute pain is your body’s protective alarm system. It’s designed to alert you that something needs attention and usually settles as the tissue heals.
Key Features of Acute Pain:
- Sudden onset
- Often linked to a specific injury or event
- Improves over days to weeks
- Tissue healing is the main driver of recovery
What Is Chronic Pain?
Chronic pain is pain that lasts longer than expected, even after tissues have healed.
Examples of this may include persistent low back pain for months or recurrent pain in your shoulder with no clear injury.
With chronic pain, the nervous system becomes overprotective, continuing to send pain signals even when there’s no ongoing tissue damage– it means the body's pain system itself has become more sensitive.
Key Features of Chronic Pain:
- Lasts months or longer
- May fluctuate or flare up
- Influenced by stress, sleep, mood, etc
Why Treatment Needs to Be Different
Acute and chronic pain behave differently; therefore, they require different treatment approaches.
Acute Pain Treatment Often Focuses on:
- Reducing irritation
- Protecting healing tissues
- Gradually restoring and improving movement and strength
Chronic Pain Treatment Typically Focuses on:
- Calming the nervous system
- Promoting and maintaining movement, strength, and tolerance to load
- Addressing lifestyle factors like sleep and stress
Understanding the difference between acute and chronic pain can help you make sense of your symptoms, reduce fear, and choose the right approach to recovery.
