@tomberry, Hello. I'm 85 and had similar experience when walking. Like you, I've always been very active until a few years ago, following two small strokes and a Giant Cell Arteritis diagnosis. Do you use a walker? That was my solution. It got me standing up straight again, feeling stable, and much more confident when I walked. My walker is the four-wheeler type and I really swear by it. My best to you. Laurie
