Sorry to hear that. It is interesting, but when I walk I actually feel better, but as soon as I'm home I'm tired, and if I stay home I sleep a lot. I live in NYC so I try to plan a different route to inspire me, but it's effort to get myself out there. My knees hurt now so it is one doctor appt after another. My husband feels more and more of his patients have this condition, then years ago when he first started practicing. Wondering if it's something in our environment. Who knows.
