Personal injury law allows a person to seek damages in several different categories, such as for medical costs. The at-fault party could be forced to make payments for past medical expenses like hospital stays, ambulance bills, and surgeries, but also for future treatments the plaintiff expects to need as a result of the accident. Putting a number on these future costs can be tricky, and the calculation usually needs to be certified by an expert. An attorney experienced in personal injury cases with catastrophic outcomes can help you gather the right evidence and acquire the right testimony to come to the right number and back it up.
