What do you want to "make it right"?

I think an acceptable resolution would be for them to complete the surgery on the correct leg, if they haven't already after they started on the wrong leg and then realized it and closed the incision and completed the surgery on the correct leg, and then offered the treatment at no cost to you.

They are probably not going to offer pain/suffering etc.

Have they offered anything??
