Legal Question in Personal Injury in California

For a claim of injury to your body, 2 years from the date of the injury or date you reasonably should have know of the injury.

Yes, two years, but there are exceptions. Medical malpractice cases have other more restrictive statute dates, and if any governmental entity might have been at fault in contributing to the injury, then there is a six month limitations to file a gov claim. It sounds like you are considering handling this claim yourself. If the injury is very minor, that might fly. If it is major, that is foolish. Any insurance adjuster will play with you if you are unrepresented, and give you low ball offers only.
