Professor Lorimer Moseley is neuroscientist, who specialises in the complexities and mind-boggling nature of pain - what it is, why it exists, how it works and when it can go wrong.
For most of us, pain is a fundamental part of being alive, and staying alive and yet none of us will ever experience the exact same pain as someone else, which makes it incredibly difficult to understand.
Every day, we stub our toes and burn our tongues. Some of us break bones and suffer from more serious illnesses and conditions.
What you feel when your skin is broken or a ligament is torn is there to tell your brain to be careful, that something is wrong and needs to be protected.
But what happens when doctors can't find any damage? When the tissues in your hips or the pictures of your brain seem perfectly fine, but still, there is agonising pain that refuses to leave you alone?
Lorimer was a physiotherapist who came to this very specific neuroscience after his own experience with chronic pain, following a pretty gruesome sporting injury that by all accounts had been fixed by surgery.
He realised that as he was learning more about how changes in the body are detected (like temperature and pressure), and communicated as pain to the brain through the central nervous system, his own chronic pain started to diminish.
Since then, Lorimer has published hundreds of papers and several books on the topic, in his pursuit to help people also dig themselves out of the hellish cruelty of chronic pain.
