Unfortunately, fibromyalgia in adults and the juvenile fibromyalgia syndrome in children are still very much a puzzle for doctors and researchers. They are finding, however, that children with fibromyalgia do have a higher rate of having anxiety disorders and/or depression disorders than children who don’t have it. It is very much a chicken-and-egg question as to which comes first, but knowing that these children do have higher rates of anxiety is helpful in treatment.
