Hi, I have just read this whole thread and you are very inspirational. I do have something to add regarding the pain discussion. I had bilateral knees the same day as your newest one. I had absolutely no pain in one and excruciating pain in the other because they said my regional block was not working correctly in that leg. I was told by the physio that you can not feel 2 pains at once. That whatever the dominant pain is is what your brain deals with. Once I had my regional blocks removed and my legs were on a " level playing field", the pain profile changed and the opposite leg was the one that hurt. This leg has continued to be my "bothersome" one. From my limited experience, this has appeared to be a very simple, but clear description of what I felt.
Sorry to take the thread back a few weeks, but I thought it was apt.
