There are 2 possible reasons for this.
1. Fat storage distribution
Your body has areas where it likes to store fat. On some people the areas are very unevenly distributed; i.e., a woman with a big abdomen and big breasts but almost no hips and stick legs, or the converse, a woman with tiny chest and abdomen but very wide hips and big legs. The cells in those areas will take up fat easily, but metabolize it very slowly.
Even after lipo, the remaining "fat storage" cells in the area will continue to accumulate fat, until such a time most of them have been suctioned away, then secondary areas of fat storage will start taking up fat.
2. Scarring and fibrosis
This is also likely. The fact that you still swell frequently means you have scar tissue interfering with lymphatics. The trouble with Laser and ultrasound lipo is that the extra heat energy used to melt fat also causes some damage to the tissues left behind. The body has to heal this slowly.
The public is not aware of this, but when laser and ultrasound lipo "melt" fat, they also melt the fat in the cells that protect nerve fibers (Schwann cells). This can cause pain.
