title: Pain and pain relief in fibromyalgia patients followed for three years.
abstract: OBJECTIVE
  To examine the natural clinical course of pain in fibromyalgia (FM) and patients' reports of the use of interventions for pain relief.
  
  
  METHODS
  This prospective 3-year study examined pain, and the treatment thereof, in a cohort of 82 women with FM, of whom 59 (72%) were reassessed on 3 subsequent occasions. Pain was measured by the following parameters: visual analog scale (VASpain), tender point count (TP), and the occurrence of widespread pain (WP). Function was assessed by the Health Assessment Questionnaire and the Fibromyalgia Impact Questionnaire, and depression and anxiety by the Arthritis Impact Measurement Scales. All treatments for FM were recorded, and patients identified the treatment that they believed had helped their symptoms of FM.
  
  
  RESULTS
  Pain reporting as measured by all parameters decreased significantly for the whole group over the duration of the study. The mean VASpain decreased from 66 to 55, the mean TP count decreased from 13.5 to 10.5, and the number of patients with WP decreased from 100% to 63%. VASpain correlated positively with TP and WP. One third of patients experienced a reduction in pain by at least 30% from baseline as well as a better outcome in overall status of FM. There was a decline in the use of prescribed medications, whereas the use of alternative products increased. Physical treatment modalities were more often perceived to be of benefit than prescribed medications.
  
  
  CONCLUSIONS
  We have observed a spontaneous improvement in pain reporting and less medication use in FM patients, suggesting that the course of this condition may be more favorable than has previously been reported.
