Our amazing nervous system has the ability to modify itself in response to stress and stimulation at an amazing pace. This has pros and cons of course. It means that you can learn a new language or, to juggle, for example. It sometimes means that we become sensitised to sensory stimulation that is in no way threatening to us.
The complexity of this is astounding and this explanation is over simplified.
Physiotherapists are perfectly placed to help chronic pain sufferers. It takes a detailed assessment and a detailed understanding of the nervous system to extract the relevant issues that contribute to an individual’s pain. Treatment in some senses can be quite conventional. Exercises prescription, occasionally manual therapy, but most importantly the advice and education given. The way a physio can explain the meaning of a person’s pain too them, is often the key. Without this, pain perpetuating behaviours won’t change.
