Documentation is everything when it concerns receiving a fair settlement from an insurance company. Your medical providers will keep records of all visits and treatments for your injury, but you should record the ways your injury has impacted your personal and work life. Only you can testify to the pain you feel, the limitations you have in your workplace, home life, personal relationships, and recreational activities. Record all of these things as well as all activities you find that you can no longer engage in and other ways your injury has impacted your life.
Writing down your observations of injuries and losses when they are fresh in your mind will allow you to recall a greater number of details, and details mean compensation. No one else will do this for you.
