I can recall an elderly neurologist presenting an undergraduate lecture in the early 70’s on peripheral nerve problems. I remember it because of a comment “somehow you guys have to let a bit of light, a bit of air into the peripheral nerves”. I have used this piece of figurative language frequently in clinical story telling, especially within the field of neurodynamics. The nervous system is bloodthirsty – it is only about 3% of body weight yet it will consume 20% or more of the available oxygen. There is more on ischaemia in Explain Pain, but for now, here is a clinical story on letting the light in – number 45 out of 71 educational nuggets and 15 novellas from Explain Pain Supercharged.
