Re: some numbness from cam boot?
Pretty much normal, but pay attention to your pain. your body is always talking to you, especially when something's not as it should be.
I did notice that when I finally got out of one of my braces, I had to pay closer attention to how my knee operated while walking. I Had become accustomed to it working to make up for the lack of motion in my ankle, and when the brace came off and I could walk without it, my knee would sometimes try to bend the wrong direction, hinging toward the front instead of bending to back as I took a step. I think hyperflexion is the term.
We're all different, so pay attention to your body talking to you and mention it to your doctor.
