The terms myofascial pain, fibromyalgia and fibrositis are critically examined. They constitute diagnostic labels for non-specific musculoskeletal aches and pains. Analysis of the evidence shows that none of these labels is substantiated by hard physical signs or by laboratory evidence of consistent pathological or biochemical abnormality. What is the objective evidence for disorder(s) of muscle, fascia or fibrous tissues, so clearly indicated by these diagnostic names? Alternative terms such as 'regional pain syndrome' or 'chronic pain syndrome' merely redefine the clinical problem without providing a mechanism or basis for diagnosis. Despite different diagnostic criteria, these conditions, along with chronic fatigue syndrome, have many demographic and clinical similarities, most notably tender trigger points. Indeed, the terms are often used interchangeably. There are few differences in the symptoms, physical findings, laboratory tests, functional status, psychosocial features and psychiatric disorders. This paper seeks not to deny the existence of aches and pains, but to critically examine the utility of these terms. The only claimed physical sign is the presence of tender trigger points over muscles or muscle attachments. Research suggests that tender points are a measure of general distress related to pain complaints but separately associated with fatigue and depression. They are present in some normal subjects and are variable in occurrence in time in the same individual. They reflect no demonstrable pathology. It is therefore argued that none of these commonly used diagnoses represent distinct disease entities. A possible but unproven alternative hypothesis is that such symptoms relate to neural pain with both peripheral and central components, and in some instances psychological or wilful embellishment.
An association between nasal septal mucosal contact points and facial pain has often been quoted, but may be coincidental. CT scans of 100 consecutive rhinology patients were examined for contact points, and the sinuses were scored according to the Lund-Mackay system. The patients' nasal symptoms were recorded using validated questions. Contact of the nasal septum with the lateral nasal structures was identified in 55 patients. The presence of contact was significantly (P < 0.01) associated with nasal blockage and reduction of smell, but there was no association with facial pain. The median Lund-Mackay score for scans with contact was significantly greater than the score for scans without contact. Whereas the results of the study support the hypothesis that nasal contact may impede ventilation and drainage of the paranasal sinuses, the study finds no evidence to support the concept that contact points cause facial pain or headaches.
