During the procedure you may experience sensations of pulling, tugging, mild pinching, intense cold, tingling, stinging, aching and cramping at the treatment site. These sensations may subside as the area becomes numb. Following the procedure, side effects include redness, swelling, blanching, bruising, firmness, tingling, stinging, tenderness, cramping, aching, itching, skin sensitivity and numbness. Numbness can persist for up to several weeks. A sensation of fullness in the back of the throat may occur after submental treatment. Rare side effects such as paradoxical hyperplasia, late-onset pain, severe pain, freeze burn, vasovagal symptoms, subcutaneous induration, hyperpigmentation and hernia may also occur. As with any medical procedure, ask your medical practitioner if the CoolSculpting® procedure is right for you.
