I did mine at KKH a few years back, and honestly the procedure itself was more uncomfortable than painful, like a sharp pressure feeling that passed quite quickly. From what I recall, they do contact you regardless of the results, so you are not left wondering, but it is worth confirming this directly with your doctor or the team who scheduled your procedure since clinics can have different processes. It might help to also ask them upfront about the timeline for results so you have a clearer idea of when to expect the call, because the waiting is really the hardest part. Hang in there, you are doing the right thing by being prepared.
