Injuries to the neck, spine, or shoulders most commonly found in rear-end automobile collisions, caused by a sudden and violent movement of the neck, are often referred to as soft tissue injury. Whether from a car accident, truck accident, motorcycle accident, or other accident, any soft tissue neck injury or back injury warrants a thorough medical evaluation. Too often people don't seek treatment for injury symptoms from an auto accident until more serious complications develop. Even after accident victims settle their insurance claims, many report they still suffer from neck and back injury symptoms years later.
