Try and occupy your mind with research and stuff you can do in your down time. The mind is in high gear and the body is in park.
I had major surgery in April 2013, definitely not fun! Best advice I heard, figure on being able to do half of what you feel like you can do. It does get better and you will notice little victories daily. I celebrated when I could look down and see my feet (the swelling went down). When I had hernia surgery it felt a little weird for a week.
It DOES get better, just not on our time line. Rest when you need to.
Praying for you.
