Thank you for your question. CoolSculpting is a safe non-invasive method for permanent fat removal. Having pain and tingling after treatment is a side effect of treatment, this can last for a few weeks. However, anytime you are having pain near the appendix it is best to be seen by your treating physician to make sure nothing else is happening. Best of Luck!
There is a small percentage of patients who have post procedural pain. However, coincidental problems can occur and this should not be brushed off as this until it is fully evaluated by your doctor. It is possible to get appendicitis at anytime, and it would be completely unrelated to the procedure. Please have it looked at to make sure it is nothing serious. The CoolAdvantage handpiece is supposed to have less of this pain afterwards.
