For years, I did not like going down stairs because my legs shook lightly. It's getting worse, so I have to go down very slow. And I also don't like escalators any more because I feel wobbly on them, with my legs shaking while standing still.
What's odd is for a while, I've also had what feels like increased muscle or a tightening/heaviness to my thighs. Yet, my legs are getting weaker. Does anyone else experience this?
