Just joined all you other ladies after having an unsuccessful hysteroscopy 3 days ago. I only wish I had known about this beforehand.
Never before have I experienced such extreme pain. I have had 3 natural births and previous surgeries. I too was not warned how painful it could be. The consultant did spend a few minutes telling me about the procedure and that I could stop it at any time I felt "uncomfortable". In the event, he called a halt as he could not dilate my retroverted cervix. He tried manually to move it and also tried to "grab"it with instruments. His words. I have spent the last 3 days experiencing flash backs and now I have to return to do it all again under a GA. This procedure should never be carried out without anaesthetic in the first place.
To everybody facing this-say no unless you are offered an anaesthetic.
