Abstract:
Fibromyalgia and chronic fatigue syndrome have similar clinical and demographic features. We found that most patients with chronic fatigue syndrome have a tender point examination similar to patients with fibromyalgia. Similar pathophysiologic mechanisms are also being explored in each syndrome, including a potential role for viral induced immune dysfunction.
