My 23 yr daughter just had one,,,, and not to scare anyone, but it was Barbaric!!! They gave her now sedation.... the numbing medication applied to the skin, before they make the incision, wasn't even administered for more than 20 seconds before the DR cut her!! It was horrible.... I would defiantly ask for some sort of sedation, or be put under.
However, what I have been reading every person is different. Some sites say it is uncomfortable and children can tolerate the pain.
