Ditto, ditto, ditto, Ed! I have mentioned "certain times of day" to my doctors but never elicited much of a response besides, "Mmm, that's interesting." My overall balance, similar to what you say about yours, is never first-rate; I'm always having to be careful. But also similar to yours, mine is often worse (more challenging) in the evening, which I, too, attribute to a full day's leg fatigue. A night's sleep, fortunately, gets rid of that fatigue. Numbness in one leg or both? I'd have to say both––although I'm a bit hesitant to call it "numbness;" what I feel is much the same sort of leg weariness I used to feel after running 10-15 miles: muscle achiness, especially in my quads, and knee unreliability, like if I do pay my knees strict attention they might just go out on me, or "flamingo" (bend the wrong way). Of course, this may be numbness, just a different manifestation than I imagined. –Ray
