Persistent Pain and the Nervous System: What’s Actually Going On?

Persistent pain can be confusing and frustrating, especially when imaging looks “normal,”  or symptoms don’t follow a predictable pattern. Many people begin to wonder whether the pain is being missed, misunderstood, or dismissed.

In reality, persistent pain is often less about ongoing tissue damage and more about how the nervous system has learned to protect the body.

Pain Is a Protective Signal

Pain is not an accurate measure of damage. It’s an output of the nervous system designed to keep us safe. When pain becomes persistent, the nervous system can remain in a heightened, protective state, even after tissues have healed.

This doesn’t mean the pain isn’t real. It means the system is working overtime.

The nervous system may become more sensitive to movement, pressure, stress, or even everyday activities. This can make symptoms feel inconsistent, widespread, or unpredictable.

Why Symptoms Can Feel So Varied

When the nervous system is on high alert, people may experience:

• Pain that moves or changes location
• Increased muscle tension or guarding
• Fatigue or difficulty recovering from activity
• Dizziness, breathlessness, or a sense of “air hunger”
• Heightened stress or anxiety around movement

These symptoms are common in persistent pain and they make sense when we understand how closely the nervous system, breathing, and movement are connected.

The Role of Breathing in Nervous System Regulation

Breathing is one of the most direct ways the nervous system receives information about safety or threat.

When breathing becomes shallow, rapid, held, or overly effortful, it can reinforce a state of vigilance in the body. This doesn’t cause persistent pain but it can maintain it by keeping the nervous system in a heightened state.

Supportive breathing, on the other hand, helps signal safety. Ideal breathing isn’t about taking big breaths or forcing relaxation, it’s about allowing breathing to be adaptable, efficient, and responsive to the moment.

This often includes:

• Gentle rib cage movement in multiple directions
• Coordination between the diaphragm, abdominal wall, and pelvic floor
• Breathing that can shift naturally with rest, stress, and movement

When breathing supports the nervous system, many people notice subtle but meaningful changes: reduced muscle tension, improved tolerance to movement, better energy regulation, and a greater sense of ease.

How Physiotherapy Fits In

A physiotherapy approach to persistent pain is not about pushing through symptoms or correcting the body. Instead, it focuses on creating safety and capacity within the system.

This may include:

• Gentle movement to reintroduce variability and confidence
• Hands-on techniques to help with joint movement and tissue mobility
• Breathing strategies that are paced and individualized
• Education that helps make sense of pain rather than fear it

Moving Forward With Compassion

Persistent pain is complex, but it is also changeable. Understanding the role of the nervous system can reduce self-blame and open the door to a more supportive, sustainable approach to care.

At Move Authentically Physiotherapy, in Kingston, Ontario, we work collaboratively, helping you explore movement and breathing in ways that feel safe, respectful, and aligned with your body.

Healing doesn’t come from forcing the system to relax. It comes from giving it enough support to feel safe enough to change.
