Hi roller, my leg pain has improved with a specific exercise I use to strengthen my legs so I can do stairs.
I lean against one of those big exercise balls against the wall placed at the middle of my back and I squat 20 times as deep as I can. (Don't have your knees go beyond your feet.) I couldn't squat very far for a while, now I can squat deeper.
I've gone from not being able to use steps very easily and feeling clumsy on them to doing the steps with more ease. But not enough ease to ever live in a place with stairs. For me, it's the weakness issue too.
Good luck to you.
