Well, I think that is what they tap to do the epidural . I was there when the Anesthesiologist did it. My wife had all three of our kids completely natural NO DRUGS at all. She was up and about within a few hours of each. She even tried to talk our daughter out of getting the Epidural, but to no avail. I cut the cord on all my kids.
right, theres a small window where they have to do it, if they miss that window, and clip something else, its not good. You need to get her to a different doctor, different specialist ASAP.
