It is common for back, neck, and head injuries to get worse over time, and not heal properly without medical treatment. Another problem with delaying your medical care is that the liability automobile insurance company for the negligent party may argue that your injuries are not related to the accident caused by their insured. Also, the more time that passes between an automobile accident, and the first time you see a medical professional, the doctors may be less able to say that your injuries are related to the automobile accident.
