Does laser treatments on Fungal Nails hurt?

As the light passes through the nail it is increasing the temperature of the nail bed. Some people feel a warm or hot sensation during this time. The laser has a refigerated air tube that you control and are able to direct towards the nail if it becomes uncomfortable.
