Dear Renee, We use either a scarless tummy tuck or a simplified tummy tuck under local anesthesia, in which such problems do not take place. Since tummy tuck was carried out without the use of drains, there can be several possibilities, looking at your post-op picture ( 8th day ). It can be a hematoma, seroma, seroma and hematoma or excessive post-operative swelling, if you are not using any post-op compression like abdominal belt. However, the last possibility is least likely, since the swelling is involving not only your abdomen, but also your flank, hip and thigh areas. You should contact your surgeon ASAP !
