Do I have a Seroma? Lower abdomen never flattened out after liposuction (Photo)

You will need an examination to see if you have an organized seroma or residual fat that can be removed.

Hi Witty65263, sorry to hear about your result. Looking at your pictures, you may have a seroma, but unfortunately it is not possible to say for sure without an in-person examination. In addition to a physical examination for signs of a "fluid wave" (and/or other tactile signs of a seroma), the use of ultrasound imaging would provide the answer for sure.
If you do have a seroma from a procedure 10 months ago, it may need to be surgically removed. The body can form a capsule around a seroma which is called a "pseudo bursa," and which makes it almost impossible to treat with needles alone. If this is the case, by removing the bursa through a small incision (that can be hidden within the bikini line), it will possible to achieve your goal of having a flat stomach.
On the other hand, if there is no seroma on examination, you may simply have an irregular contour after liposuction, which would require secondary liposuction to treat. I hope this helps, good luck!
