Report your accident, and ask for medical care.
The first thing you have to do is report the injury to your employer. You should also be careful to document exactly who you told, when you told them, and the circumstances under which you told them. If you've been injured, you should also request and obtain medical care, and be careful to do each and every thing that the doctors tell you to do during your recuperative process. When that's over, you should be evaluated by a physician who can determine whether or not you've sustained a permanent injury or a permanent loss of function to one or more parts of your body. An experienced workers' compensation attorney can provide vital insight in guiding you through those various steps in the process.
