Book excerpt: Millions of people experience symptoms of central sensitization (CS) and central sensitivity syndromes (CSS) such as chronic fatigue syndrome, fibromyalgia and multiple chemical sensitivities. Yet many lack diagnoses, education and resources. Without proper support, some patients may become withdrawn, suffering needlessly and possibly developing mental illness. Covering the syndromes within the context of central sensitization (CS), this book provides candid personal experience, strategies for symptom management, and suggested methods for coping and long-term healing, with easy-to-understand science.
