At 1 to 2 weeks after treatment, there may be redness, bruising, and swelling; tenderness, cramping, and aching; itching, skin sensitivity, tingling, and numbness. In some cases, numbness may persist for several weeks after a treatment. Talk to your doctor if these side effects persist past 2 weeks or worsen over time.Rare side effects include:
- Paradoxical hyperplasia: Visibly enlarged tissue volume within the treatment area, which may develop 2 to 5 months after treatment. Surgical intervention may be required.
- Late-onset pain with a typical onset several days after a treatment and resolution within several weeks.
- Freeze burn: First- and second-degree freeze burn may occur during treatment. It typically resolves without sequelae with proper care.
- Vasovagal symptoms: Dizziness, lightheadedness, nausea, flushing, sweating, or fainting during or immediately after the treatment.
- Subcutaneous induration: Generalized hardness and/or discrete nodules within the treatment area, which may develop after the treatment and may present with pain and/or discomfort.
- Hyperpigmentation: Hyperpigmentation ( dark spots light spots) may occur after treatment. Typically, it resolves spontaneously.
- Hernia: Treatment may cause new hernia formation or exacerbate pre existing hernia, which may require surgical repair
