The law states that there is no fixed standard which exists for deciding the amount of pain and suffering damages. This is good news: the law is flexible, and can adapt to each case, which will have unique harms and damages. You will not be put into a box or an algorithm as far as the type or the amount of your damages.
However, on the other side of the coin, the lack of a fixed standard can make proof of damages tricky, and highly subjective. It is important to discuss your unique harms and damages with a personal injury lawyer who is experienced in all aspects of personal injury, including trials, to develop a strategy to best prove the amount of your damages.
