Central Sensitivity Syndrome
The concept that several of these related conditions should be grouped under the unified heading of Central Sensitivity Syndrome was first presented by Dr. Muhammad Yunus, rheumatologist, professor of Medicine at the University of Illinois College of Medicine at Peoria, and pioneer in fibromyalgia research.
Dr. Yunus discovered that many of these conditions (e.g., fibromyalgia, myofascial pain syndrome, irritable bowel syndrome, chronic fatigue syndrome, headaches and restless legs syndrome) shared several characteristics, including pain, poor sleep, fatigue, extreme sensitivity to stimuli, and an absence of abnormal tissue structure. The connecting thread for these conditions appears to be central sensitization, which simply means that the central nervous system has an exaggerated response to stimuli.
Although research has made great strides in recent years, it will probably take many more years to fully determine what the similarities and differences in these conditions mean.
