Salinogram?!?

He

Any ladies have a salinogram? My RE is doing one on me this upcoming Saturday I’m just trying to know what to expect. Funnily enough I’m actually an X-ray tech so I’ve done sooooo many HSGs as a technologist (not as a patient), but I’ve never actually seen a salinogram I think mostly bc they don’t do those in the hospital they do them in the doctors offices. Should I expect it to be similar to a HSG? I understand the process of the salinogram its basically a HSG but with water but do you feel that it hurt more or less than a HSG?
