Dreaded Phone Calls

I dread the middle of the night phone calls. Every once in a while our phone will ring after midnight and it will be a wrong number. For a while we turned off the phone in our bedroom but it's since been turned back on.
At 1:30 this morning the phone rang. Seeing as it's on my husbands side of the bed he groaned and then reached over to answer it. I'm all about answering the phone in a somewhat pleasant voice. His "what" came out pretty rude. It was downstairs Debbie telling him that Mom needed to go to the ER. It seems that there is some infection in her incision. He told her he'd be right there,laid back down and sighed. He hates hospitals. I got up thinking I'd be the one going and was told to go back to bed as I had done enough already with taking care of her. Off he went.
I've gotten one update so far. They took her for a CT scan-she's on an IV and she's sleeping. In fact he mentioned that downstairs Debbie is also sleeping and he's watching the CNN news that one of our friends is so fond of.
Downstairs Debbie is going to need a vacation after Mom is recovered. She's not in the best health herself and has been running ragged with taking care of her. (since the other sister checked out).
So four hours later they still sit in the ER waiting for the next step. In my opinion they should admit her to clear this up. Some things just can't be taken care of at home. Seeing as she sees fit to self medicate herself-at least in the hospital she can be given what she needs when she needs it. I was there yesterday for a few hours and didn't notice anything that would cause concern. She was walking around pretty good and in a good mood. Didn't complain of any pain or discomfort. Hopefully this is just a minor set back.
