How does a needle of small diameter typically feel to the patient during treatment?

In the context of electrology, a needle of small diameter typically feels hotter to the patient during treatment. This sensation arises because finer needles provide a more concentrated energy output at the tissue level. As the treatment involves the application of heat to the hair follicle to destroy it, smaller needles direct energy more precisely, which can create the perception of increased heat during the procedure.

The sensation of heat can stimulate nerve endings in the skin, contributing to the patient's experience. It's essential for practitioners to be aware of this sensation, as it can help them manage the patient's comfort levels and adjust treatment techniques accordingly.

A larger needle may distribute energy over a broader area, leading to a different sensation. However, the focused energy from a small diameter needle is what contributes predominantly to the perception of increased heat during treatment sessions.
