My trial was on the operating room table, which is not the usual way, so I really can't tell you how your experience will be. This was my 12th surgery, and, as you've had serious surgeries, I can assure you that you will get through your trial just fine. You may be uncomfortable, to be sure, but it won't be anything like what you've experienced right after a hip replacement! I will pray for you tomorrow, and will check back to see how it went for ya!
