It is normal to feel some lumpiness this early after liposuction. There's swelling and tissue inflammation. Based on the limited view photos, I'm more concerned about the unnatural grooving across the lower abdomen than the lumpiness. These areas were over suctioned and you most likely will end up with oblique grooves across the abdomen. It is fine to place depressions in certain ares, such as the border between the lateral rectus muscle and the obliques, or a slight depression in the mid-line from the breast bone to the belly button. All these emphasize an athletic looking abdomen. Your grooves are unnatural. You need to wait at least 6 months for a possible revision. At that point, traditional liposuction might not be able to give good improvement. In my practice, I do a significant number of secondary liposuctions after patients had suboptimal surgery elsewhere. I use the VASER to release the scars and often employ fat grafting to improve the results. These are very difficult to correct completely. That is why is so important to choose a board certified plastic surgeon and not a cosmetic surgeon with different surgical or even non-surgical backgrounds, poor training and understanding of tissue healing. Good luck, need to be patient now. Too early an intervention will further detract from your results.
