What can help reduce swelling, after gynecomastia lyposuction surgery?

Its been 10 days since my surgery. About a week ago, was the first day I took off my foam vest. When I took it off, I noticed how well and flat my chest looked. Now since I took off thr foam, my chest is a little numb, and a lot swollen. It almost looks like old chest before my gynecomastic surgery. Is it just the swelling or am I getting man boobs again? Is there any way to reduce the swelling? I also have to mention that I have taken off my vest multiple times and have left it off for a few hours.
