The million dollar question is does it hurt? Yep it sure does! Varying from a mild irritation to a sharp smarting (but still bearable) sensation, but just look around, if it was so bad would we all have so many? And in 80% of cases return for more ! Dereck's advice is Be sure you enter the studio in a relaxed state of mind - don't come in after a night on the tiles. Be sure to eat a little a few hours before your appointment. Don't bring a friend to accompany you inevitably this will add to your stress and will annoy or distract the artist.
