I'm the poster who asked before whether my arm liposuction turned out well. Looking back at my previous post, it really has changed a lot. The accessory breast tissue is gone too, and I got the straight, right-angled arms I wanted.
However, just as I was worried, I don't think the back part is completely gone. It's still bulging out. But it's not severe enough to get revision surgery, so I'm just going to live with it. I'm satisfied that I can wear the sleeveless tops I wanted as much as I like haha
