I had my gallbladder out Laproscopically and went back to work after 2 days off, had it our Monday afternoon and was back to work on Thursday morning. I never took a pain pill except the first few hours after, when I tried to turn over the stitches pulled and it was uncomfortable...no real pain or anything just the uncomfortable stitches. I only took 1/2 of a Darvocet-N 100 at that.
I also have had exploratory surgery this way, looking for Endometriosis, then later to take care of scar tissue and adhesions in my abdomen.
I have had no serious effects other than a bit of discomfort due to them pumping my abdominal cavity very full of he gas so they could see everywhere the Endometriosis was. I ached like I had over exercised a bit. Again, just some general discomfort, no real pain.
