My uncle is out of the hospital. Apparently, they couldn't find any clots with any of the other tests they did, but the doctors did find that he was dangerously low on magnesium and potassium. They pumped him full of those yesterday, and released him last night. He may have to go to Denver in the next couple of weeks for his foot (he's got some diabetes-related issues with a wound on his foot, and his specialist is in Denver), but with any luck he won't have to go back into the hospital again for a long, long time.
*whew!* I'm with my aunt - I can't wait for things to be boring again!
