I have been staying off my butt and only sitting in the BBL pillow but lately I've been having a lot of tingling and my but looks like its half the size it was last week. I'm now 13 days post OP. I'm worried that sitting in the BBL is straining my booty and that is why I'm losing it so fast. I keep having tingling all over my butt. Since it's so early is it bad that its unswelling so fast. Should I be worried about losing more then 40% of the fat?
