Yes, I have painful legs and knees because of my gait. I do the "zombie walk" first thing in the morning and when I get up from sitting for an extended period of time. After several steps I can resume a somewhat normal gait.....or more normal than the one I have upon first rising.

I tend to tense up when I walk in places unfamiliar to me because my balance is off. Especially outside areas and big stores. At home I can walk pretty well but I'm sure it's because it's familiar territory and, for the most part, flat.
