Legs getting weaker by the day. In the evening my walking is very awkward and choppy. Strangely enough I walk much better in the morning. Muscle twitches are beginning to show in my left arm. I find myself taking deep breaths more and more. Sometimes my eyelids will stick close. I've not had leg cramps in the morning since I began mild exercise and stretching of my legs on a recumbent bicycle but I will get them when I get up from a lying position if I'm not careful during the day. The legs that used to power racing bicycles up steep long hills 7 years ago are dimpled and puffy looking and of course twitching, twitching, twitching. I don't know what this "thing" is, I do know it's fast.
