Is losing feeling in your fingers a side effect of CoolSculpting?

CoolSculpting is FDA-cleared for the flanks (love handles) and abdomen and is proven to be a safe and effective treatment. Typically, there is minimal to no downtime after the treatment though patients may experience temporary pain or discomfort. Side effects can include redness, bruising, swelling, tenderness to the touch, cramping, itching, tingling, and numbness. Numbness can persist up to several weeks after a procedure. If numbness were to occur as a  result of CoolSculpting, it would occur on your stomach, not your hand.

There are side effects with Coolsculpting and they are typically minimal compared to the consistently excellent results. The symptoms you describe would not be related typically to any Coolsculpting treatment and thus suggest you follow up with your family doctor for evaluation.
