question: I am a 57 year old female. When I sit for any length of time, whether it be 5 minutes or 5 hours, I have difficulty walking. I also get a lot of pain on the outside of my right leg. Another thing, when I sit or lay down, shocks bounce back and forth all over both legs and feet constantly. It never stops until I get up and move around but the second I lay back down, it starts again and is continuous. Do you have any idea what could cause this?
