I had my surgery last January. Pain can be controlled, (somewhat for me). I had problems.
1) Problems with anemia until I finally got a blood transfusion 3 or 4 days after surgery.
2) Severe constipation. PLEASE eat when the dr. says to. I was so sensitive to smells, that all food produced a gag reflex and I did not eat for so long my bowels stopped working. When I was finally able to eat, nothing would get them working again so I spent an extra 5 days in the hospital being given 3 different, but very strong laxatives to get things going again.
3) Got an infection after being home a little over a week and then I had to head back to the hospital for another weeks or so.
Bring a pillow to the hospital so that you can hold it against the incision. It helps with the pain, particularly when coughing.
Get up an walk as soon as possible. With my problems, I was only up and walking on day 5 and that was because my doctor challenged me.
I dont know your sisters symptoms or how close you are...but, I had terrible juandice and itched everywhere. After surgery, my leg hairs had grown in enough that they were itching and causing the itchy feeling from the jaundice to kick in overdrive. My mom shaved my legs for me because the incision prevented me from doing so. Instant relief!
Your sister will start to get sensations back in here stomach several months after surgery. These can be from a mild, numbness like when your foot falls asleep, a feeling of hot or cold, or an intense bee sting feeling.
Ask the doctor about getting some antacid type medicine as the new plumbing causes a "bubbly" feeling that isnt so nice.
Peppermint tea helps some with the upset stomach after surgery. My nurse was a big pusher of it.
I am the worst healer and it took me 9 to 10 months after surgery before I felt like my old self, though I was still at about 50% physical strength and I would get tired after about 15 minutes of real play with a child.
Best of luck.
