I am finding that I am becoming more and more unsteady on my feet. I have become afraid to walk outside unassisted because i start feeling weak and light headed and need some kind of support. I am thinking of trying a walking cane. I used to be able to walk for about 10 to 15 minutes by myself on a good day. Now, even on a good day, I need my husband's arm to hold on to for support. Has anyone been using a walking cane?
