Seriously? You think the hospital is going to lie about the cause of her condition? I don't think so.
Hospital has only commented on her current condition. Her spokes people are the only ones who mentioned anything about about a concussion,previously. Like I said,never have heard of anyone being put on bedrest for 3 weeks with a concussion,especially someone who has a history of clotting. They want you up and about for everything. I'm not saying she should have been up running a maraton,but even,the before mentioned Dick Cheney showed his face after a couple days.Think of Reagan after nearly dieing after being shot,he came to the hospital window) There is a reason she was not seen for 3 weeks. (maybe its as simple as when she fell down,she was badly bruised).
I don't think there is any grand conspitacy,just question how healthy the poor woman really is.
