Allen,
The only thing I remember noticing was occasionally triping going upstairs, on carpet and differnces in sidewalks and road surfaces. I never had a hollow feeling just a weakness in not being able to lift my foot up ( tap my foot) or even lift my toes off the ground. My right side was stiff from the glutes down and right ankle was weak. The feelings I get now in my legs and arm are almost like a pumped feeling in my biceps and forearms and a crampy feeling and my muscles feel like they are crawling or rolling somtimes.
