There is an interesting article in the NRC newspaper about chronic pain. In the article, a researcher is interviewed, a neurologist, a neuro-immunologist, an anesthesiologist/professor and an expert from Pijn-Hoop about chronic pain. People no longer see 'chronic pain as acute pain that has lingered, but as a complex condition in which the nervous system is disrupted at various levels'. “Chronic pain, all pain experts say, is a bio-psycho-social problem.” 'A new insight is the role of the immune system' in actively turning on or turning off pain.
