Pain is something that most people experience at some point in their lives. Whether it’s temporary or persistent, pain is primarily interpreted by the brain. When an injury occurs, signals are sent from the nervous system to the brain, which then creates the sensation of pain.
However, there is an important distinction between acute pain and chronic pain. Understanding this difference allows for appropriate treatment and optimizes recovery.
Acute pain: a normal warning signal
Acute pain usually occurs as a result of an identifiable injury: a wrong movement, a blow, excessive stretching, a sports injury, etc. It is a normal reaction of the body to physical damage.
The healing process takes place in three main phases:
1. Inflammatory phase (24 to 72 hours)
The body sends the cells needed for repair. Redness, heat, and swelling are normal during this period.
2. Proliferation phase (up to about a week)
The tissues begin to repair themselves and fill in the lesion.
3. Remodeling phase (several weeks to several months)
The fibers gradually realign to restore strength and function to the tissue. This phase can last up to a year, but pain is generally no longer present during this entire period.
In clinical classification, pain is considered acute when it lasts from a few days to a month. Between one and three months, it is classified as subacute. Beyond three months, it becomes chronic.
Chronic pain: when the body adapts… sometimes poorly
Pain that persists for more than three months causes more profound changes. The nervous system can reorganize itself in response to constant painful stimulation. The body develops protective mechanisms, postural and muscular compensations.
For example, a shoulder injury can lead to unconscious changes in posture to avoid pain. Even once the injury has healed, this compensatory posture may remain. Over time, muscle tension, joint restrictions, and imbalances set in, perpetuating the pain.
There is often a psychological component as well. Fear of moving or aggravating the situation can limit movement, which contributes to maintaining the problem. The body then becomes “programmed” to function in an inadequate pattern.
Chronic pain is therefore no longer linked solely to the initial injury, but to all the physical and neurological adaptations that have developed over time.
Why interdisciplinarity is essential
Whether pain is acute or chronic, an interdisciplinary approach offers significant benefits.
Acute pain
The goal is to optimize healing and prevent chronicity.
Quick intervention allows you to:
- Promote effective tissue repair
- Gradually introduce movement and strengthening
- Limit compensation
- Reduce the risk of persistent pain
The earlier pain is treated, the easier it is to manage.
Chronic pain
Treatment must be comprehensive. It may include:
- Manual therapy (chiropractic, osteopathy, massage therapy)
- A strengthening and rehabilitation program (physical therapy, kinesiology)
- An approach aimed at managing fears and apprehensions related to movement
The goal is to gradually “undo” protective mechanisms that have become maladaptive and restore more natural and balanced functioning.
When should you seek medical advice?
Pain that persists for more than two to three weeks warrants evaluation. Even if the injury seems minor, early intervention can speed up recovery and prevent compensatory mechanisms from setting in.
Understanding the difference between acute and chronic pain allows you to take action at the right time and choose the appropriate strategy.
