You have a case as long as you have an injury that costs money to treat. Always receive a comprehensive medical exam after a car accident or similar incident just to rule out whether or not you have an injury. Some injuries, like a traumatic brain injury (TBI/concussion) and whiplash may not show up for days after an accident. Some people feel fine immediately after an accident only to develop a limp or partial disability in the future. You may not “feel” hurt, but until a medical examiner rules out any injury, you could still have one.
Furthermore, you can file a complaint (lawsuit) based on property damages alone. These cases usually do not have as large of damages compared to injury, but they can benefit individuals who aren’t being offered a fair settlement for vehicle repairs or personal property replacement after an accident.
