Your brain is a bunch of factories

Let’s imagine that your brain is an industrial city. A hive of activity. Areas of the brain are separate little factories, and each little factory is responsible for manufacturing certain goods or coordinating specific services.

There are some certain factories that have a sideline in processing pain. If we are lucky, they are only called into action to do this every now and again, in acute pain. In acute pain, extra factory workers (known as neurones) are recruited temporarily from their usual activities to undertake the sideline tasks of processing and managing pain. Because these workers are taken from the main factory tasks, the other outputs and purposes of that factory temporarily slow down or stop. Fortunately, in the short term, there is minimal disruption to the usual factory purpose. After acute pain dies down, it goes back to business as usual at the factory.

But what happens when the pain continues, stealthily moving from acute to chronic pain? What happens when those factories are called on to process pain more and more?

Well, simply put, the sideline job takes over from the main goods production. More and more of the factory workers (neurones) are recruited to manage the influx of pain messages. More and more of the factory floor (brain space) is dedicated to managing pain, and less space is allocated for producing the main goods of each of the factories.

Factory processes (neural pathways) are altered to focus on pain, taking the emphasis away from business as usual. In short, the sideline becomes the main job.

Frequent or constant pain messages wire up the brain to dedicate more and more space to processing pain. In acute pain, only 5% of space in relevant brain areas is dedicated to pain-processing. In chronic pain, however, that goes up to 15 to 25% of the space in those individual factories.

But, what do I mean by the “relevant” brain areas? Well, not all of the brain processes pain. Finding out which areas of the brain are involved in processing pain gives us a clue as to how to fight it.


Pain should be like a welcome houseguest

Pain should be like a welcome houseguest: It’s handy to have around…but even better when it leaves!

Short-term acute pain is an important warning system.  When acute pain slides into chronic pain, however, lives change.

Acute pain is a natural phenomenon. We need it for survival. Pain sends a strong message to our brain that something is wrong. It protects us by forcing us to stop what we are doing and instigating healing processes.

Let’s say you are walking on the beach and misjudge your footing in the soft sand, twisting your ankle. Suddenly, you feel a sharp pain shooting up your leg. That sharp pain is the signal for your body to stop and protect yourself. The pain stops you from standing up. Then, the tissues around your ankle begin to swell, protecting the joint more by restricting any movement. The swelling also increases the blood supply to the ankle, bringing white blood cells to mop up the damaged tissues.

Your body mounts response to prepare to flee or fight to survive. Your blood pressure rises, which might cause you to feel faint. Your digestion slows down so your body doesn’t waste energy digesting your lunch. And, your immune system focuses on the injury, which means there is less energy left to fight other infections. Right now, your brain considers your injury more dangerous than any other cold or flu that is floating around. All of these consequences of this initial ankle injury are designed to force you to protect yourself and survive.

All of this is perfectly fine and natural … in the short term. And, it would be logical to think that once the immediate danger has passed, our brain would stop the warning signal, let go of the pain and life would go back to normal. However, for reasons that we still don’t understand, some people, including myself, slide into chronic pain.

Chronic pain is pain lasting longer than 12 weeks. It can be caused by many conditions, even those you might consider insignificant or minor. The slide into chronic pain usually occurs silently and sneakily. Not everybody has the same path into chronic pain, nor the same lifestyle restriction, but the following indicates how easily this slide can happen.

Let’s return to the ankle injury on the beach.

So, you have twisted your ankle on the beach. After you catch your breath, you might hop on your unaffected leg to the nearest rock and sit down. You take the next few days off work, and then you use crutches to get around when you return to your job. Obviously using crutches is difficult, so you try and alter your work tasks to reduce standing and do more at your desk.

Using crutches to get around is tough, so you cancel the trip to the movies you had planned with your friends. Cooking is also a little tricky when you are on crutches, so you get take-out ‘just for a few nights’, rest on the couch and catch up on Netflix.

Fast forward six months and that ankle is still giving you trouble. For reasons that the doctors can’t explain, your ankle still hurts, even though no damage shows in any of the tests/X-rays/MRI scans that you have. Your doctor increases your pain medication, which makes you drowsy, but that is better than living with pain.

You are too drowsy from the medication to concentrate for too long, so you stay home most days now, watching TV. You are worried that if this pain does not go away soon, you will run out of money. You even had to cancel your Netflix to save money.

This ‘warning signal’ of pain is carrying on too long. And if that sounds like your story, finding a way out can be difficult. “Rewiring pain” might challenge you to think about how whether you have slipped into a pain lifestyle, and it will provide some answers as to how to get back out.



Lisa’s Blog

Hi and Welcome.

As you may have noticed my website has changed because I have taken on a new project. I am excited to announce the launch of my new book “Rewiring pain”. I hope you like it.

Here in this blog, I will write about a range of things, starting with chronic pain and neuroplasticity.



Revisiting the scene of the crime

I have just returned from a work trip to Thailand. I know, that sounds nice. But in 2013, my chronic pain life began on a flight home from a work trip to Thailand. My spinal nerves became irritated because I didn’t move enough during the flight. So you can see how I would have been nervous as I flew home last week.

When I say “chronic pain life”, I’m not kidding. Chronic pain takes over your whole life in one way or another. For me, I spent almost 2 years with chronic stomach and back pain which meant that I spent those almost 2 years:

  • wearing elastic-waisted pants
  • staying on the couch instead of having a social life
  • dragging myself through the work day
  • working my way through most of the pain relievers available to my doctors
  • watching more television that one person needs in a lifetime!

The good news is I found a way out of my chronic pain life, and back into the life I wanted to lead. I wrote a book to help others.

Here is a link to a quick video about how it came about that I wrote a book on Getting out of chronic pain.



(PS. I made sure to move around a lot on the recent flight home. I’m happy to say, I’m fine this time)


Is it possible to crochet your way out of chronic pain?

When Paralympian and Doctor of Clinical Science, Dr Lisa Chaffey, experienced unrelenting pain in 2013, she didn’t guess then that her love of craft would act as a pathway back into living her life almost pain free.

A wheelchair user all her life, Dr Chaffey’s world changed dramatically when she slid from acute to chronic pain. Her pain was due to a spinal nerve sending a mistaken pain message, but her brain responded to it as if the pain had a physical cause, known as neuropathic pain.

She spent the following two years looking at research for a way out of pain and is now sharing her very personal and informative story in the hope it may help others. What she found was a new and exciting view of changing how the brain processes pain, using neuroplasticity (the brain’s ability to change itself).

“Rewiring Pain, a new way to reclaim your life” describes Lisa’s journey into and out of chronic pain, and provides a step by step guide, using everyday activities and habits to spark neuroplasticity.

The basic idea is to create brain pathways that compete with pain for attention. The exciting discovery outlined in this book is the focus on the receiver of the message (the brain), not the sender (the body part). Anyone can use this book regardless of the cause of pain.

A Deloitte Access Economic report commissioned by PainAustralia found 3.24 million Australians were living with chronic pain in 2018.  The report put the total economic cost at $73.2 billion AUD including costs to the health care system and productivity losses.

However, the cost is much more than financial. Lisa’s own experience attests to this. Her experience of chronic pain included multiple trips to doctors and specialists as each ruled out specific diseases and possible causes for the debilitating and recurring pain. As hope dimmed, her world narrowed to the 200 metre radius of her couch.

“I tried desperately to cling to my normality and how I wanted to live my life but my mantra became ‘i just can’t do it’.  I was angry because I was beginning to lose everything I had worked for and I was fearful of the future,” she said.

An occupational therapist and academic researcher by training, Lisa used her famous stubbornness and grit and stumbled on emerging research in neuroplasticity. That revelation changed her approach to the way she was managing her pain, which is where her love of creative pursuits came in handy.

“It wasn’t until I started researching brain function that I saw the neuroplastic potential of craft and creative pursuits,” Lisa said. “Brains are wired and rewired by what we do and retraining the brain is possible with determination and taking a different approach in everyday activities, including doing simple things such as knitting, writing or even cooking a fancy dinner.”

In “Rewiring Pain”, Lisa uses her own experience of chronic pain in conjunction with the research she uncovered, to outline practical advice and tips in changing the way the brain responds to pain.

The book is broken into three sections, culminating in the development of a ‘pain plan’ to help those with chronic pain find a way to manage using everyday activities.
