I feel I need to add my two cents to this thread. My AN was large and located on my left side. My left side was affected due to the size of the tumor. I had trouble controlling my left arm and hand, actually my entire left side immediately after surgery. I went to physical therapy and occupational therapy which has helped quite a bit. Sometimes when I am tired I find my left hand is shakey. I guess I just figured this was a normal side affect of my surgery. It does not happen to me on a regular basis. I am doing exercises my PT gave me and they help, once again patience is required to get through this life changing event.
Also, I would like to comment on the Right Side/Left Side comments previously entered. When I got home from my two week stay in the hospital and rehab. We discovered I could not feel hot/cold or pain on my entire right side, also my blood pressure was slightly elevated. When I spoke with my surgeon, he said my tumor was so large, that when they removed it they tapped my brain stem (he called it a brain stem insult) and that is why I am having trouble on my right side. So yes, the left side does control the right and even though the location of the tumor should not affect your functions, things can and do happen in surgery that can affect your outcome. I am now 9 months post-op and just starting to feel hot/cold in my right hand only, my blood pressure has returned to normal.
