You should go to the doctor immediately after a car accident. Even if you are only a little sore on the day of the wreck. Even a small impact causes the occupants to sustain several thousand pounds of force, and most folks feel like they have been run over by a train 48 hours after a car crash. Equally as important, if you “tough it out” and don’t go see a doctor, or go to the emergency room, you won’t have medical documentation to support any potential claims. The insurance company will likely dispute your contention that the accident caused your injuries. They do it almost every time, even when it is quite obvious that you have suffered injuries from a wreck. It is important that you continue to see the doctor every time that you hurt so that he can document your injuries, and do the proper testing.
