Generally, CoolSculpting is not painful. The cold sensation at the beginning of the treatment may cause some discomfort, but the area quickly becomes numb for the remainder of the treatment. At the end of treatment there is a 2-minute massage that may cause temporary cramping or tingling, but this subsides within a few minutes. There is a small percentage of people that experience tingling or stinging in the days after their treatment due to the nerve endings waking up – our doctor can issue temporary medication to minimize nerve pain for those who experience this.
