Developed Fupa and Scar Tissue after Lipo surgery. What needs to be done to fix both problems?

I Developed a Fupa after Liposuction, it feels like I have a very thick layer of scare tissue infront of my whole abdomen. I also believe that I have scare tissue fused to my Diaphragm because its hard for me to breath sometimes when I talk. Please tell me what should I do. This is very frustrating!!! And it’s been 4 years after surgery!!
