I can tell you its not fun. Not only is it painfull, but to me its kind off embarassing. I can't believe at the age of 42 I have to use the hand rail to climb the stars at home, I feel like a 80 year old man. I've always had some kind of back pain, but never to this extent. The pain is not even in my back, it's my hip and leg that are the problem, It's a strange deal.
