What is the Best Way to Get Rid of Fibrosis After Liposuction?

I'm from Mexico, so, sorry for my english. I had my first liposuction two years ago, which left me with fibrosis and fat pockets on my waist, back and abs. I got a liposuction revision three days ago with tumescent technique. The next day I already had a huge banana shape fibrosis on top of my belly button. I'm going to start ultrasound therapy tomorrow, but I want to know the best treatment available to get rid of it. I'm really scared that it will stay again. What's your best advice?
