I forgot to mention the issue of driving. That was also a concern of mine. I still have C1-2, though it is not so good. I also have T1-2. You need both of them to drive. I have trouble looking over my shoulder as it is. I no longer drive distance or at night. short trips is really all I can do and be safe. If you can keep C1-2, or T1-2 you would be in better shape to be able to drive. C2- T3 is a very long rod, and turning around would be very difficult. Do ask your doctors about this, and get as much information as you can. I am sorry you are going through so much. ginnie
