I was involved in a motor vehicle accident. I was stopped at a red light and someone hit me from behind. My neck and back are hurt and i am currently in PT. 10 years ago i was also involved in a motor vehicle accident where i substained bad neck injuries as well. Can i sue if my neck was reinjured? Is there a simple formula to follow to calculate what i should be suing for? ex: medical + pain/suffering + lost wages.... My medical bills are currently at 2500.
