I see their commercials here too.
Go ahead and try them, it won't cost you anything. If they don't think that they can win, they will not take your case.
I am considering the same thing, I can't work like this anymore. Last year, I had carpal tunnel and cubital tunnel surgery and was on sick leave for three months. The pain at home was alot less, than the pain I suffer when I am at work. And the fatigue is easier to manage at home too, you can sit or lay down when you need to and not push yourself, like you have to at work.
I say, go for it.
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
