During the period of post-treatment swelling, the area can look fuller than it did before treatment. As the fat cells are disrupted and the inflammation subsides, most patients see results by 6 to 8 weeks after a treatment. The swelling can appear to be more severe than the double chin fat that was present. It is not abnormal for the swelling to temporarily cause a burning, tight and numb sensation. Patient’s have also reported feeling lumps during the healing period that resolve as the swelling subsides. These symptoms should resolve themselves as the swelling subsides. Cold compresses and Tylenol can be effective for pain relief.
