What should I tell the doctor after my Florida car accident?

First and foremost you tell them what’s bothering you. You need to report all of your injuries, all of your pain and symptoms to the doctor so they can keep track of what they need to worry about and how they can best care for you. If you felt the injury three days before you saw the doctor and some of the pain went away, I would still tell that doctor what injuries you had three days before. Let the doctor worry about what’s bothering you now, let the doctor inquire about what problems you’re still having so that they can give you the right treatment.
