Tsuniya, who asked me before whether the arm liposuction went well, I saw that things had changed a lot after reading your previous post. The floating room disappeared and it became the right angle arm I wanted. However, it seems like the back part isn't all missing as I feared. It's still vague. But it's not serious enough to require reoperation, so I'm just going to live with it and I'm satisfied that I can wear sleeveless clothes as much as I want haha.
