My gramma is in the hospital.

She went to the doctor yesterday cuz she was having trouble breathing. They took some x-rays and said she should go to the hospital. The decided to admit her. I don't even know what's wrong. It could be that she had too much fluid in her lungs, but if that was the case they could've just drained it and sent her home the same day. It could also be a problem with her heart.

I'm a little worried.
