Hysteroscopy for polyp removal

Hi all, I just got scheduled to get an endometrial polyp out, measuring about 5x8mm. My doc said it’s not small but also not huge. I think it’s the culprit of causing a poking pain during sex at certain angles for the last 2 years.

During my ultrasound today, she put a catheter up into my uterus after dilating me to inject a little saline in to see the polyp better. When she inflated the balloon at the end of the catheters, it must have started poking the polyp - I literally screamed. It was HORRIFIC. So painful. I yelled stop I can’t do it and she deflated it but luckily was still able to see the polyp just fine. I was not expecting how painful that was, it was terrible. So now I’m a little nervous about the hysteroscopy, she said they would knock me all the way out for it though with general which I appreciate, don’t think I could do it otherwise.

What should I expect for the surgery? Any significant pain after?? Like I said it’s just 1 medium size polyp so I’m hoping it’s a smooth process…
