Talked to my mom and my dad today. The doctor did find clots that had traveled to his lungs, and he's now on heparin. They said he's got some kind of clotting issue. The doctor also said that they've found he has Deep Vein Thrombosis in both legs. This is not good news. I'm not sure what they are going to do for this, in the long run. Dad seems in good spirits though, so that's good.

He should be home on Saturday, so hopefully we'll know more before then.
