Karl sent me an email earlier today and apparently it was just fluid in his head. They were able to drain some of it (yes...that's gross...) which helped a lot to reduce the swelling and make Karl more comfortable. I'm not quite clear if the incision is still bleeding but Karl's email seemed to suggest that a lot of it was just general fluid. I haven't been able to speak to him directly yet.
If you would like to spend some time with Karl during this upcoming week that would be great. He's just really bored at home with nothing to do. You can email my sister at karizawada@hotmail It may be easier to email her to set up a time since I'm back in Boston now.
