Lump Left After Coolsculpting?

Thank you for your question. Depending on the applicator that is used and the size of the area, the surrounding skin can protrude if not applied correctly. I would recommend double stacking if the fat is in the same area, which means doing another Coolsculpting session the same day. I would recommend being treated under the supervision of a Board Certified Dermatologist or Plastic Surgeon for safest and best treatment options. I hope this helps.

It is not unusual to see localized swelling within fat tissue from the inflammatory process that involves the removal of the fat. This can occur weeks to even a couple of months after the procedure. It tends to go away with time, although external massage, lymphatic massage, and external ultrasound energy devices (the latter used often in post-surgical patients) can help reduce the lumpiness.

True cases of enlarging fat tissue are very rare, but have been reported and the cause of this paradoxical fat enlargement is unknown.

It is possible for a lump to appear in the treatment area several weeks after your procedure. It could be inflammation that will gradually dissipate or, as your doctor said, it could be fat. It is best to allow some time to determine whether the lump will resolve on its own. If it's still an issue after 4-6 months, your doctor should take a look at it again and see if there is a need for a repeat procedure. For now, I recommend monitoring the lump before having a second procedure.
