I went for my CD3 testing this a.m., I now have to schedule a HSG. My papers state I am supposed to call some radiology group, but it doesn't say who? It says I will have received instructions on which radiology group to call. They also gave me a piece of paper with the name of a Dr. in Lake Success named Dr. Kalra and I have no idea why. I left a message and I am waiting for a call back now, but to those of you who had this, who do I schedule it with?I vaguley remember them telling me soemthing about Mather Hospital, but they handed me so many things I am just confused now!
