I have not had that surgery but I have had others. As in all recovery goes, movement is key to rehab. Yes it will be painful, but the more you do it and the more you push yourself the faster you will rehab and the better the results you will have as well. Do the exercises the Dr. or therapist tells you to do and dont go overboard with it at first but build yourself up to more and more, you will be glad you did in the end.
