Oh honey it sounds really uncomfortable. I also had heaps of swelling down there, for quite a few weeks beforehand. I did have quite a bit of irritation from rubbing etc, but probably not what I would call grazing iykwim. It's hard to say what you should do... If it has come on all of a sudden then I would probably call the hossy, or if it is unbearable then I would. I guess I would just follow your gut instinct. Sorry I'm probably not much help... GL
