Help! Is this tummy swelling from fat donor site after 6months post op normal? (Photo)

Hi, I had a fat transfer from tummy to breasts after implants were removed. Since fat transfer (i was not given or told to use compression garments) tummy has not felt right & has been constantly swollen. Will swelling ever go? Has something happened in surgery that shouldn't have? I also have a hard lump now just above my belly button. I am supposed to be undergoing more fat transfer to make breasts same size due to asymmetry but I am scared in case tummy gets EVEN bigger??
