I've had 2 hysteroscopies, including last October because of a thickened womb lining and excessive bleeding. I had a GA both times because I find smear tests excruciating, to the point that I've had to abort them.
The consultant conducting the procedure said I should never have been put on evorel conti, and recommended the coil, which I had fitted at the same time as the hysteroscopy. It's stopped the bleeding, which is great. Consultant agreed that when it's due to be removed, this can also be done under GA if that's what's best for me, and she's put this on my record. Luck of the draw whether you get a supportive consultant, as I didn't get the same offer when I had a previous hysteroscopy.
I worry a lot about medical procedures, but glad I had the hysteroscopy, as I got the all-clear, which gave me peace of mind.
