Abstract
Subjects with chronic, diffuse, unexplained muscular aching were recruited--21 from a primary care practice, nine from a rheumatology practice, and two from a pain clinic. No additional criteria were used to select subjects. Subjects with mild or moderate symptoms differed from those with severe symptoms with respect to the following characteristics: the presence of fatigue on awakening, the number of tender points, difficulty in sleeping, and the degree of tenderness in typical fibromyalgia areas as measured by a dolorimeter. These findings suggest that muscular aching is likely to be of greater severity if other symptoms or signs of fibromyalgia are also present.
