I read on another site where a person suggested that during the trial period you try to do things you couldn't do before, to see if it really will help when you get the permanent implant. The downside is that if you do push yourself, and it takes a while to get the permanent one in (waiting on insurance approval, waiting on a surgery date, etc.), then you may be in more pain than before the trial. So make sure the dr. is willing to help with increased pain while you're waiting on the permanent implant.
