I had my brachioplasty done 4 months ago. I am extremely happy with the results.
The worst part of the whole ordeal were the drains and the swelling. The drains were only in for about 1 week and the swelling lasted about 4 weeks before it wasn't noticable anymore. The pain was very mild.
Yes, I have a scar down the inside of both arms, but I was aware of it going into this procedure, and like my doctor said, you have to be willing to trade off the flappy skin for the scar. My doctor did a fantastic job of placing the scar on the underside of my arms, and unless I raise my arms, you can't see the scar.
