I also broke my wrist this summer and somehow I also ended up anemia with only 4 units of blood in me --not the 12-15 required to live. One day I just about passed out and my wife took me to the emergency room----next thing you know I'm in the hospital for 3 more days. Nobody knows where the rest of my blood went. I had NO "bleeding from anywhere' They did a colonoscopy and an endoscopy both and all my plumbing checked out fine. They gave me 5 units of blood and blamed it on a blood thinner was taking for my heart and took me off that. All in all it's been a hell of a summer. I finally got back on my motorcycle a couple of weeks ago. That's the only thing keeping me sane.
