Plastibell Circumcision

Does anyone have experience with this? The new pediatrician we have preferred that a pediatric urologist do it so we went to All Children's Hospital. This is my first baby that has had this type done and I'm freaking out. He screams when I change his diaper. I'm assuming it's because the diaper sticks but she told me not to put anything on it until the ring falls off. They told me to give him 1.25ml of Tylenol but it's not really helping him. I wish like hell they would have just done it in the hospital like my last son. It didn't bother him at all. He didn't even cry ???
