What is Cryo Nerve Block?

Graphic of countries

Cryo Nerve Block involves freezing the nerves located in your chest underneath each rib. These nerves are one of the main sources of pain after chest surgery, and cryo nerve block helps by temporarily shutting off the nerve. With Cryo Nerve Block you’ll have a sensation of numbness after surgery, which means a lot less pain.

How does Cryo Nerve Block work?

Your nerve has two main parts, an outer protective structure and the actual nerve that senses pain. By freezing the nerve at a specific temperature, it is disabled without damaging the protective structure. This allows it to regrow right back where it was before. Over several months, your nerve gradually regrows, about one to two millimeters per day or about the thickness of a credit card. The numbness will slowly go away and normal nerve feeling resumes starting from the side and going towards the sternum.
