Like you, I'm double jointed in my thumbs, fingers and wrists(well, I was until I got old
) and I get horrible pains in my joints. I just attributed it to arthritus and age. And the fact that my 2 jobs keep me on my feet on concrete for up to 15 hrs a day, is why I figured my ankles never stop aching. I never dreamed d-j's would cause all this pain. That's very interesting.
