[So, is 40k reasonable, or do I hold out for more??
Then, if I did agree to the 40k, is that on top of the back pay TTD lump sum that I got last Spring after the judge ordered them to pay me, or do I deduct that TTD amount from 40k and now receive the remainder????

I don't know about the TTD or how the future medical might work out, I hope someone else can help with that, but your atty really should be the one to explain those details to you so you can decide on any next steps.

Each case, state, laws are so individual, not to mention attys & judges & drs.

mine was just a straight forward - sign here and we'll pay you x amount and you are on your own after that.
