Sorry ladies not a particularly nice subject but wondering if anyone else gets horrible rectal pain when on your period? I get mine on and off for a few days each time. It feels just like someone has shoved a knife up my bum, it takes my breath away and often makes me feel nauseated. I was just wondering if anyone else has this symptom with their endo and how they manage it at work? I can be in a meeting and it comes on suddenly, its obvious something is wrong with me so I have to say its pain I my back. Can't really announce the real problem!
