I had this yesterday - it wasn't as dreadful as I'd feared but still very unpleasant. Towards the end of the procedure I had a very sudden sharp pain like something popped inside me or I was given a sudden prod. I shrieked very loudly, leapt about a foot off the bed and I was so shocked I started blubbing like a baby! It was pretty clear the consultant and nurse didn't think anything had happened to cause such a reaction and nothing more was said after they'd calmed me down.
I've been taking nurofen but by the time I went to bed last night I was in agony and could hardly walk. This morning it is better but I'm still in considerable discomfort and walking is painful and difficult. (imagine an old croan bent double stumbling along)
If I lie still in bed it's ok though.
Has anyone else had such an extreme reaction? I had expected mild period pain but this is nothing like period pain - it feels like I've been kicked several times in the stomach by a horse!
