Trend: Another case of Blackberry thumb, doctor?

Heavy use of handheld devices is leading to a new generation of repetitive strain injuries, according to physician reports. Among them is a new condition labeled "Blackberry Thumb" by specialists. Like many other hand-held devices, the Blackberry asks users to perform ergonomic tricks which may not be good for them, using their thumbs to execute many commands. Heavy use can lead to problems. Happily, like other variants of carpal tunnel, the condition is treatable with rest and appropriate anti-inflammatory medications.
