Hi Molly is back. I had my total knee replacement September 23. I have been going to physical therapy twice a week since then was progressing nicely. Good range of motion and flexion. However, Monday I was having some nerve pain on the left side of the new knee and upon doing repetitions of standing from sitting, without help of hands, after about six of these, my leg buckled with increased pain up the outside tband I felt such nausea and pain. More than I’ve had during this whole recovery. I am now back to not being able to stand without help, Walker, etc ugh
