My sister had to take my BIL into the hospital to see the doctor today.  They called him in.  I guess they're going to try to get him a CT and do more bloodwork.  He's also developed an atrial fibrillation (irregular heartbeat)...and is quite weak and dehydrated.  Poor guy is having such a hard time.  There's a possibility they might admit him.  He hates the hospital but he's in tears now and saying he doesn't want to go home, he's scared, and doesn't feel well.  Please keep him in your thoughts and prayers.  My sister is tired and stressed but is coping.  But I know she's having a hard time too.  I'm even getting a bit scared about this.  I wish there was more I could do...someway I could make him all better.
