7/2     What are knee braces used for? If I have something like a cramp in my
        knee (hurts a little when I bend my knee), would walking around in a
        knee brace help?
        \_ Go see a doctor. In the meantime, wear the brace and drink
           more water.
        \_ ice and heat. rinse repeat.
        \_ A brace is for more serious injuries...for now, do what they
           said wear one of those cuffs made from that thick spandex-like
           stretchy stuff.
           \_ I never understood what these did. What is the benefit to my
              knee of wrapping it in some tight material?
