@centre thanks for the good info. I had not thought of asking someone to help me with curbs. I also have balance issues with both legs with right leg worse. I try to do exercises every day, in bed, walk 30 minutes on treadmill or outside. I started having knee pain a few months ago and it was getting worse. I decided to do some exercises every other day. That worked. Now no pain in knee. I feel much better using a cane. Without it I would now be frightened to go up and down a curb. I use a cane to walk a short distance outside and have a walker in my car for longer time away from home. I believe the exercises I do help very much. I am wondering if anyone has symptoms as follows. If I lean my head over in the morning or where there is lots of light I have double vision. It subsides when I pick my head up. In the afternoon I do better. If I try to read small print I shortly have double vision and, when I walk too fast I also have double vision. And I cannot walk very fast. I have had this for more than a decade. I assume it is part of the nerve damage. When I told a neurologist about it he did not address it. Just went on talking about other things. Does any one know anything about these symptoms? Thanks for listening.
