Chronic Pain Management: Understanding the Pain Cycle and the Role of Psychology

What may have started as relatively mild lower back pain can gradually become something that feels much bigger, something that affects you physically, mentally and socially. A light touch, a short walk, or a normal day of chores may trigger pain severe enough to leave you in bed for days.

You may have found yourself having scan after scan, only to be told that ‘everything is normal’ or that there are only minor changes. Understandably you may wonder “How can I be in so much pain if my scan is fine?”

While scans can provide valuable information about the structures of the body, they don't always explain how or why someone experiences pain. Chronic pain is complex, and understanding it requires us to look beyond structural damage and consider the interaction between the body, brain and nervous system.

Pain can become louder when the nervous system stays on high alert.

Pain is Protective

Pain is a protective mechanism. Think of it like a smoke alarm: its job is to detect potential danger and alert you when something might be wrong.

When you first experience an injury, this alarm is helpful. If you break your leg, for example, pain discourages you from walking on it and potentially causing further damage while the body heals.

But what happens when the alarm becomes overly sensitive?

With chronic pain, the nervous system can become hypersensitive, becoming increasingly responsive to signals that were previously considered safe or harmless. Like a smoke alarm going off when you make toast.

The pain is real. The alarm system has simply become more sensitive to potential threat.

This increased sensitivity can develop over time. When pain persists, the nervous system can become more responsive not only to physical sensations, but also to factors such as movement, stress, poor sleep and fatigue.

Signs of a sensitised nervous system can include:

• Pain that spreads beyond the original area

• Pain that flares after small activities

• Sensitivity to touch, pressure, temperature, or sound

• Fear of movement because flares feel unpredictable

• Increasing stress or anxiety

  
  

This does not mean we ignore symptoms and ‘push through’. It means asking a better question: “How can I help my system feel safer again?”

Desensitisation starts with safety, not force

When your nervous system has become highly protective, trying to force yourself through pain isn't necessarily the answer. Instead, the aim is to gradually provide experiences of safety and build confidence in your body's ability to cope.

This might involve:

• Slow, controlled breathing

• Developing greater awareness of physical sensations without immediately interpreting them as threatening

• Gentle, manageable movement

• Gradually returning to activities that have become difficult

• Improving sleep and stress management

• Challenging unhelpful thoughts and predictions about pain

  
  

Small, repeatable movements can help the body relearn safety.

Breaking the Boom-and-Bust Cycle

One of the most common patterns in people with chronic pain is the boom and bust cycle. You have a good day and feel determined to make the most of it. You exercise, clean the house, see friends and catch up on everything you've been unable to do. Then the pain catches up. You flare, become exhausted and spend the next few days recovering in bed.

Pacing breaks that cycle by planning activity before pain makes the decision.

Pacing involves finding a sustainable level of activity and gradually building from there.

For example, if 20 minutes of walking consistently leads to a significant flare but 8 minutes feels manageable, you might begin with 6–7 minutes and gradually increase over time.

Pacing isn't about doing less forever. It's about building capacity without repeatedly overwhelming the system.

Rebuilding a Life Around What Matters

Chronic pain can gradually shrink your world.

Work becomes harder. Social plans are cancelled. Exercise disappears. Hobbies are put on hold. Relationships can become more difficult. Eventually, it can feel as though life has become organised around managing pain.

Part of recovery is gradually changing this. The question shifts from “Can I do the whole activity like I used to?” to “What version is possible now?”

Perhaps it's seeing a friend for 30 minutes rather than an entire afternoon. Walking for 10 minutes rather than an hour. Returning to a hobby in a smaller, more manageable way.

This matters because meaningful activity gives the brain richer information than pain alone. Enjoyment, connection, purpose, and confidence can all help the nervous system settle.

Valued activities can return in smaller, more manageable forms.

Moving Towards a Different Relationship With Pain

Managing chronic pain doesn't mean ignoring symptoms or forcing yourself to ‘push through’. It means learning to understand your pain differently and gradually changing the patterns that may be keeping your nervous system on high alert.

The aim isn't necessarily a completely pain-free life. It is more choice, more confidence and more participation in the life you want to live.

Psychological therapy can be one part of this process. Working with a psychologist who understands chronic pain can help you make sense of your experience, identify the patterns keeping you stuck and develop practical strategies that are tailored to you.

You don't have to wait for the pain to disappear before you start getting your life back.
