Whether there is any discomfort during electrolyses is quite variable depending on a your tolerance, machine settings, modality used, as well as other factors.  During most treatments a definite sensation should be noticed.  It has been variously described as a "slight heat", "tingling" or "stinging" sensation.  I am trained to work within your  comfort tolerance.  Don't hesitate to let me know what you are feeling.  Working together we can achieve the greatest results with the least amount of discomfort.
