I had a BBL in December 2022 and due to a large fat pocket that formed on my left cheek I had to return and have revision in March 2023 (this year) which they used liposuction to remove the fatty lump. all seemed fine until 2 months ago when the liposuction area felt tender and warm on occasion to touch. There is slight bruising or discolouration as it doesn’t hurt in surfacing areas except in the surrounding areas when pressed it feels quite deep. Is this a lipoma or something else?
