Aim: This study aimed to investigate the effect of working time on cold and fibromialgia syndrome symptoms. Material and Methods: The study included 568 individuals with a mean age of 36.9 years. Visual analog scale (VAS), The Revised Fibromyalgia Impact Questionnaire (FIQR) and 2016 Revisions to the 2010/2011 fibromyalgia diagnostic criteria were used for evaluation. The groups were formed as 2 years or less, 3-5 years, 6-9 years and 10 years or more. For daily working hours, two groups created as less than 8 hours and 8 hours or more. Results: It was found that the score for VAS pain felt when working was higher compared to pain felt when resting (p=0.046). FIQR scores increased significantly in the cold work year (p=0.006) but there was no significant change in resting or working pain as working years increase (p> 0.05). FIQR total score, resting and working pain VAS values were found to increase for the group work more than 8 hours daily (p <0.05). Discussion: As a conclusion, the results of this study showed that increasing working years and daily working hours caused an increase in the severity of FM related symptoms. Especially those who have been working for 10 years or more and/or more than 8 hours in cold were feeling greater pain and their fibromyalgia related symptoms were worse.
