Do you have a lawyer? Because there are arguments to be
made for past and future pain and suffering, not to
mention one needs to know what an insurance company is or
is not likely to pay out.
Get an attorney if you don't have one, he or she can
advise you concerning the specifics of your case. I'm
sorry I can't be of more help, but it's really not
possible to know what is reasonable unless one has access
to all the facts. Nor am I an attorney.
