Hi Sue. Thanks for responding. See my response to John. I don't need any walking aids as my balance is pretty good. My strength is pretty good, even when fatigued. If that makes any sense. The pain I can deal with. Some days recently, after some breakfast and take a shower, I feel almost completely exhausted. This started about three months ago. On better days when I cut the lawn, my thighs start to ache. Is this part of arthritis? Have to sit down and message then. Seem to return with new energy. Didn't have this problem last summer, although my arthritis pain is about the same. Ted
