Hi Patboy. I've had this procedure done. A word of caution, please ask for some sort of pain killer. My doctor did mine without anything and to be completely honest, it was extremely painful. I don't want to scare you, I just want you to be prepared. She told me that to numb me would hurt even more, so she usually doesn't even bother. I wonder if I would have agreed. It is a fairly quick procedure. That is the good news. And once it is done, you feel no pain at all. In fact, I went to work afterwards. The insert a very thin tube through your cervix and into your uterus. They fill your uterus with saline. You can't feel that at all, just the tube in your cervix. Then they insert the camera. If they don't see anything, the procedure is over. In my case she found a tiny polyp and asked if I wanted it removed. I told her yes as I never wanted to do this procedure again. This took a little longer and definitely was painful as she scraped my uterine lining to get the polyp. The nurse let me hold her hand which was helpful. I did a lot of deep breathing which also helped. Once the procedure was done, I could feel the saline gush out of me. That felt strange but didn't hurt. I had very little bleeding afterwards, more like spotting. I got fairly dizzy after and they made me lie down for 30 minutes, have some juice and crackers. If you feel dizzy, make sure to let them know. It is common apparently. After that, I was fine. I didn't feel any residual pain. The whole thing including the polyp removal was probably 20 minutes tops.
That all being said, I'm very glad I did it. It helped answer questions I had. I thought I had big cycts/polyps/fibroids, but I didn't. If you are going to be awake for the procedure, take some ibuprofen an hour beforehand. Don't take it if they plan to put you to sleep. Good luck and let us know how it turns out.
