Central sensitivity syndromes (CSS) are stress, pain and fatigue syndromes, and environmental illnesses,  that cause unpleasant symptoms. The symptoms can mimic those experienced by people with autoimmune diseases, neurological disorders and psychological disorders. 

In CSS abnormalities cannot be seen with a microscope or a picked up in standard medical tests.  Some abnormalities however may be picked up. with functional pathology tests or a SPECT Scan.

Central Sensitisation can be explained as

problems at the level of the brain and spinal cord (CENTRAL)

A nervous system in a wired, wound up and hyper-excitable state due to the way neuro-endo-immune cells communicate chemically and through other mechanisms.  (SENSITISATION)

These sensitised cells amplify , or make stronger, messages that we get from our senses. This can cause sensory stimuli that is not normally painful, e.g. light touch, soft sound to become painful.  (Allodynia, Hyperalgesia).

Examples of Central Sensitivity Syndromes?

Include those shown in the diagram below. FMS:  Fibromyalgia CFS:  Chronic Fatigue SyndromeMCSMultiple chemical sensitivity; IBS: Irritable Bowel Syndrome (IBS); Migraines PTSD:  Post Traumatic Stress Disorder;  TT: Frequent Tension Type Headaches; PMS: Premenstrual Syndroms; MPS: Myofacial Pain

This list however, is not exhaustive. For example POTS (Postural Orthostatic Tachycardia Syndrome), which many people with ME/CFS experience can also be considered a CSS.

It is not uncommon for people to develop many CSS,  over a period of time.   This is why some people can experience lots of different symptoms. Up to 50 SYMPTOMS sometimes more!

Central Sensitisation was first identified in the chronic pain and fatigue syndrome Fibromyalgia more than 25 years ago by Dr Yunus.   It is linked to having a too high stressor load.
