How much should I ask for when I was hit in a cross walk and got a broken ankle?

I lack specific information to answer your questions completely. Each personal injury case stands on its own merits, hence, there is no specific amount one would ask for given a particular injury.

Several factors will go into the non-economic damages figure. The usual calculus is as follows: What was the injury (there are many different types of ankle fractures)? What did it take to get you back to 100%? How long did it take? What were you prevented from doing during that time?
