If you've ever performed a job that required you to repeat the same motion over and over again, then you may not have realized that you could have seriously damaged your muscles and connective tissue in the process. Called repetitive motion injuries, the damage associated with such injuries can take a long time before symptoms present themselves. But in some cases, when symptoms -- such as pain or numbness -- do present themselves, it may be too late to fully correct the damage.
If you are injured on the job, the first thing you should do is seek medical attention, especially if your injury is severe. Second, your supervisor should be notified about your injury and the way in which it occurred. Next, you should complete the appropriate claim forms to participate in the workers' compensation system.
