I had the same DCIS lumpectomy, oncoplastic surgery reduction and lift on both breasts. The nerve block lasted 3 days, no pain. They sent me home with tramadol, Tylenol and Advil. I did not like the effects of the tramadol and only took it for 2 days. Took the other OTC analgesics for about a week. Very little pain.
Surgery was 3 1/2 hours with about 1 hour in recovery. I was told I could go home, 3 1/2 drive, but I wanted to stay one night in the area just in case there was a problem. Stayed at the Marriott in the medical center, lots of pillows behind me and to support my arms. I walked quite a bit the evening after surgery - they said it would be good to get up and move around. Walked for over hour through the air conditioned hallways of connecting hospitals.
The stitches were quite Frankenstein-ish! But they do fade.
I slept in a recliner for a pretty long time. And we bought an inexpensive counter top microwave because I knew it would drive me crazy to not be able to use the built-in (really high) for 3 months!
