"So my attorney screwed me!?"
I wouldn't say that. Many times when you initially present the case to them there is reasonable belief there is a viable case. Then as records are obtained and more information is verified that may change to the case is not sustainable.
I would go back to the lawyer and ask very direct questions:
1) Will the other side seek dismissal because you are covered by WC?
2) Since there is no expert medical testimony to back up your injuries and they are minor how will that affect the case?
3) If there is a settlement from opposing side will the lawyer negotiate a possible settlement on repaying WC?
4) what about taxes?
5) what do they think the case is worth?
If the answers sound too good to be true: they probably are. i.e. you have a multimillion dollar case and they will get top value for it. Is this one of those firms that advertise in billboards, full page ads in phone book, and radio spots every hour? They tend to promise the moon and then deliver peanuts.
