One of the most important witnesses in your personal injury claim is a reputable doctor. If you have been injured (whether you have a legal case or not) you should get checked out by a doctor as soon as possible. Some injuries can get worse if not treated promptly, and it is good to have a medical record of your injury from the beginning. If your injury is very severe and you must immediately go to the hospital, make sure when you are well enough that you contact the hospital for any records regarding your treatment. A doctor will be able to tell you if there will be any lasting damage from your accident, as well as what treatment you will need in the present and future. A doctor will also be able to refer you to appropriate therapists and specialists if needed. If you do need further treatment, make sure you get copies of all your medical records for your legal case.
