Yes it seems to be a normal practice. I had a D&C and uteran biopsy without any pain meds. they had someone in the room to hold my hands so I could not get up. I have to have a hysterectomy on Monday.
I had a D & C without anesthesia years ago, which I consider to be a form of barbarism. I have asked many women who have had the same procedure and 98% of them have been with anesthesia, in a hospital. The reason they do not (can not) give anesthesia for this procedure in a doctor's office, is that in an office, they are limited to what type of pain meds they can administer, by law. Granted, it is not a complicated procedure, and the pain is negotiable for some, but, I HIGHLY recommend that you have pain medication for it. Not only is it emotionally taxing, but the pain is real, albeit for a short time. If possible, go to the hospital, as an out patient. If not an option, ask lots of questions...Best of luck...
