"I just had mine put in today, I realize every experience is personal so take my review with a gain of salt. 
This was the absolute worst pain I have ever experienced. I passed out, and the moment I woke up, I threw up from pain. Mind you, my pain tolerance is such that I didn't even cry when I broke my pelvis. I couldn't even drive myself home from the procedure, my husband had to leave work and pick me up. When I got home I was on Advil AND tylonal, still 10/10 pain. 8 hours later I'm at about a 6/10."
