I have to have a discogram at L5-S1 before I have a fusion. So, I've been doing some research on what it's like and all I've read is that it's the worst pain those who've had it have ever felt. People were saying it's worse than the fusion itself! So I'm just wanting to know if anyone has had this test and what is was like. I've never been scared of a medical procedure before, but I'm kind of freaking out about this.
