Yes, i'm 24 and have had 3. The first was very small and smooth and passed with no problems. it hurt bad.
The 2nd was a little larger and jagged. The pain brought me to my knees. I had to go to the ER because i though i was dying.

My 3rd was straight to the hospital and had to have ultrasound therapy to break it up into small pieces.
