I've been having problems with my left leg since I've been pregnant; like a pinch nerve and I'm having to drag when it hurt. My doctor just said its the stretching of the ligaments. Well I'm 21weeks pregnant and just started back working in a warehouse. I'm on my feet for at least 10 hrs with breaks in between. On my first day, my left leg just gave out and I was trying to put my weight on my right which didn't make it better. The arch of my left foot aching and I'm having to drag my leg again. What's up with that
