Karen is back to her nights of broken sleep. The pain is, as you'd expect, worse than before the surgery. But she has a PCA again, so she can push a button to get morphine when the pain picks up. The downside is waking up after a short time in a lot of pain because you haven't been getting the morphine. Her heart rate is also more elevated than usual, but they say it's from the surgery.
Also, because she got the blood transfusions, she is even more immunodeficient than before, so even when she's out of intermediate care, they're asking for no visitors who are coughing or sneezing.
