It is a needle piercing the skin so there is discomfort. The degree is different for everyone. After I have gone across the area I have a topical antiseptic that does a good job. Everyone comes back to finish their procedure and usually says "Whatever the pain is, it's worth it". Also, as soon as i stop the pain stops. It is not a lingering kind.
