A recent study of Canadian workers reports a high number of people with both tendonitis and carpal tunnel syndrome (CTS). They aren't sure what the link is between these two conditions.

Maybe it's the type of work you're doing that is affecting both areas of the arm. Perhaps there's a certain body type that's at greater risk for soft tissue injuries. Repeated motions while working can irritate more than one area of the arm. Yet not everyone doing that job gets CTS. So there must be some other factors at work.

Since CTS is so common in the workplace scientists are working hard to find some answers to these questions.
