Days at the hospital

Well, this week hasn't been too fun. We took Dad to the hospital Sunday morning and he's still there. He was really weak, disoriented, and got to the point where he couldn't even keep water down. Needless to say he wasn't eating and was getting dehydrated.
At the hospital they did another CT scan, chest x-rays, blood work, urine work, etc. He's had 2 1/2 liters of fluid by IV too. They found a bladder infection and swelling in his brain. The doctors immediately started meds through the IV on Sunday and put in a catheter. On Monday Dad was taken off the IV and began taking medicine by mouth. He was also forced to walk a little, but was very unstable. Today his catheter was removed, he started eating better, and he is walking better (still with much help). Dad should get to go home tomorrow (Wed). That's the update for now. I'm headed back to the hospital now. I'll try to update more when we get home.
