The pain occurs in the luteal phase of my cycle, from ovulation until my period, sometimes a few days before when I feel the hormone shift. The pain event is almost always the same although the severity increases as I get closer to my period. The pain is triggered by orgasm, especially after I have an erotic dream in my sleep & orgasm from it...….almost right away the horrible pain starts building. Makes me afraid to sleep! The pain is also caused by arousal or vigorous sex & lasts for about 25 minutes, usually I have to poop, get sweaty, a few times have even felt like I was going to throw up. It goes away after about 25 minutes & I feel totally normal, almost even better than I did before, like something has relaxed. I also get "the pain" after my first morning pee, sometimes after a bowel movement & sometimes after getting up from sitting for a while and moving around, but again, only in the luteal phase. I also feel the same pain after exercising before my period as well. I only have light/medium bleeding during my period, so I don't think endometriosis is very likely. I did find that sitting up in bed at night with my feet elevated helps prevent the pain....which makes me wonder if this is some type of blood flow problem? I have no idea what this condition is but I have had it since my teens, I am now in my late 40's and am FED UP!!
