But despite these metaphoric analogies, a victim of an accident is not left with no recourse. If a person has been injured because of another's negligent acts then he has a cause of action against him or her. Evidence proving that the person failed to exercise the proper diligence at the exact circumstances of time and place when the accident happened may be a ground to claim against him. This is where your medical physician would serve as your number one ally.
In vehicle accidents, more often than not there are no witnesses who would testify to the occurrence, particularly because other supposed witnesses are also in transit at the time of the accident. Hence, the best evidence to prove that you were indeed injured are the prognoses made by your medical physician. This diagnosis serves as the only testimony of the resulting act done by the negligent party, and used as a basis for a valid claim.
Hence, as much as possible it must be made as precise and appropriate as possible. Work hand in hand with your medical physician, he may be your last and only chance.
