Relation of the factor to menstrual pain and musculoskeletal pain.

The purpose of the present study is to investigate the relationship between the regions of menstrual pain and of myofascial pain syndrome, which is the main cause of musculoskeletal pain, as well as to examine the changes and relationships among the menstrual pain-related factors, which are pain level, pain area, activity, appetite, mood, and sleeping pattern. The subjects were 13 sufferers of musculoskeletal pain and 17 non-sufferers. Pain diary and pain chart systems were used for the measurement of menstrual pain-related factors and musculoskeletal pain. Data were analyzed using repeated ANOVA. The results show that there are significant differences between the two groups in pain level, activity, and mood during menstruation periods (P< 0.05). The area of musculoskeletal pain and menstrual pain were found to be the same.
