After a rough couple of days, I think Mom has, in her words, finally turned a corner.
She ended up having 2 additional surgeries to stop some unexpected bleeding, and somehow along the way her platelets and hemoglobin were both low, if I have my information correct. Now, though, she seems to be picking up speed and is on the road to recovery. I talked to her just a little bit ago and she sounded quite good! She said the pain at this point isn't even that bad -- in fact, one of her biospy procedures caused more pain than the surgeries did. Crazy.
Anyway, she should be released from the hospital tomorrow, if all continues to go well. We hope her recovery is smooth and quick from here on out!
