Dr. Wolfe responds to a previous article by Drs. Harth and Nielson on fibromyalgia (FM). Wolfe believes FM is a socially constructed concept rather than a distinct medical entity. He argues FM defines patients on a spectrum of symptom severity rather than distinguishing diseased vs. non-diseased. Wolfe is also concerned about undue influence from pharmaceutical companies on FM research and treatment. Harth and Nielson fail to address Wolfe's arguments regarding social construction and medicalization of FM. Wolfe believes more consideration should be given to social and cultural factors in FM.
