1. RSD is defined as an injury that occurs as a result of over or improper use. 1 in 8 American workers has been diagnosed with an RSD at one time or another, and it’s one of the most common types of injuries at Colby College. Early recognition and treatment is key to preventing significant long term damage and to ensure a rapid recovery. There is no one clear way to know that you are headed for an RSD. Often, by the time you realize that something is wrong, damage has already been done. For this reason, try and pay close attention to your body for the following early warning signs: Pain: Workers may feel a sharp or dull and aching pain in their limbs, which may increase in intensity over time. Some employees feel this pain after shoveling or mopping for a few hours, while others start to notice it only when they make certain movements outside of work—such as twisting a doorknob to open a door or raising their arms to wash their hair. Tingling or numbness: Sometimes a worker's hand or arm may have a tingling sensation, or the employee may experience numbness or tingling in certain fingers. This is a sign that nerve damage may have already occurred, so these symptoms should be taken seriously. Fatigue: A worker who is experiencing pain may tire easily or may be unable to perform the same amount of work that they had done in the past. Weakness or clumsiness: A loss of strength, dropping items, or having difficulty picking things up can be a sign of a possible RSD.
