it appears the reason I could not walk very well is that I have a severely sprained right ankle and even more severe arthiritis in the same ankle. I am now sporting a boot on my leg which, if you have never had the good fortune of wearing before, is quite heavy. like at least 100 pounds. ok I do exaggerate but it is heavy and I have to wear it all day every day and use crutches. hump. well hopefully I will be able to walk properly after this. I certainly hope so. and I have a nasty cold. whew when it rains it pours. but at least I did not gain any weight!
