I am not aware of any permanent or long term lumps as a side effect from CoolSculpting. We have not seen this as a complication from CoolSculpting. The fat cells die and the body has to metabolize them. There is inflammation which is the body's way of reacting to clean up the area and this produces tenderness, swelling, warmth and hard lumps at times. They should go away in several weeks and your doctor can recommend some treatments to make this better sooner.
