birth control
"I'm 25 and have never had children.  A good friend recommended this to me and she had no pain.  I had a tremendous amount of pain - generally speaking I'm "tough" too.  Pinching and pressure for what seemed like an eternity when it was being inserted.  Granted, I didn't have any numbing or pain killers before. When the doctor was done I had to lay there for at least 10 min before I could get up.  Broke a cold sweat, got really dizzy, and really, really had to make a run for a bowel movement while still sweating and dizzy.  Very unpleasant.  I really thought I was going to die for about 20 min after insertion.  Then, I drove home and relaxed and slept well.  So far, so good.  Slight cramping, but that's to be expected.  I only got it yesterday!"
