Some signs are obvious while others are more subtle.
The first step is to look for these signs or clues. Certain jobs or work conditions cause worker complaints of undue strain, localized fatigue, discomfort, or pain that does not go away after overnight rest. Workers visiting the clinic make frequent references to physical aches and pains related to certain types of work assignments. These examples show that WMSDs can occur in a variety of workplaces. Alternatively, signs that the suspected problems are confined to isolated tasks and relatively few workers may suggest starting with a more limited, focused activity.
