It can take anywhere from 3-13 weeks to see your results. However, if you've only had one treatment, you will probably need another. I find that most patients require at least 2. Hope this helps.
We have had multiple patients with nodules after various fat reduction procedures. In fact, we have noticed that typically, patients who experience more inflammation tend to get better results. Staying hydrated and gentle massage on the area will help to break up those deposits faster. They should all resolve with more time.
