IME - Independent Medical Exam
AME - Agreed upon Medial Exam (the two lawyers agree upon the examiner together. This is what I had. I believe it was because I had CRPS and they both wanted a qualified Dr. so that there wouldn't be any question later that the doc didn't know what they were talking about.)

The other side wanted me to do an FCE and the AME denied it, said it would cause too much pain for me and be useless as it would only show what he had already determined.

If your lawyer wants you to get another exam it is his responsibility to find a doctor who will do it AND to get WC to pay for it.
