I am 3 weeks post left TKR on 2/17. Been working hard on rehab at PT facility as well as at home. I am 125 degrees range of motion and can stand alone on the surgical leg and throw the ball 30 times. All of this has been praised by therapist and surgeon. However, I can’t sleep at night more than an hour at a time then laying awake for 2-3 hours. I stopped oxymorons during the day a week ago and last night was my first night without any pain med before I went to bed. Encouraged by rehab but frustrated with night pain and insomnia. Is this normal?
