What you need is a dr of your own that can point out the wrong parts of the IME drs report.. Do you have a dr that will be able to do that?

Sometimes having a obviously poor IME report makes it easier for your dr to refute the points.

your lawyer needs to clarify that part for you and lawyer needs to point out problems /issues in IME report also with your own drs report & help.

The more clout & good reputation your dr has makes his report stronger than one from an IME that only sees you for a single short appt.
