The knee is never the same for very long. Two weeks ago this Wednesday was a crazy workout. I felt great, but my knee hated me. It's better now, but there is a new pain on the back side. It's always something. It will fade into the cacophony of other hurts and I'll move on to something else. I wish I felt like the pace of falling apart was slowing down. There have been definite times where the march towards disintegration has been faster than others. Not doing anything, slowed it, but it was painful. Doing stuff to keep it working, also painful. And sort of speedy.
One of these days it will slow down.
