When i'm on my period, especially on the super heavy days, I get this unbelievably sharp pain that starts in the anal area and shoots up, as if someone is shoving a sharp knife up my rectum. It hurts my anus and the area between my anus and vagina.
The pain itself only lasts 5-10 seconds (although it feels longer). I can feel it comming, and I have just enough time to brace myself. The pain comes so strong I can't breath, and it jolts me out of my seat. It is the WORSE pain I have ever felt. This tends to happends in clusters. It feels like maybe a muscle is being pulled or a nerve is being pinched just inside my anus, and gives the sensation that someone is shoving a sharp object into my anus. It really feels like I might pass out or die.
I've done countless hours of "googling" but nothing matches my symptoms or situation. Also, I have an IUD, but I got this pain before the IUD, although it is worse now.
What is causing this pain? is it dangerous? what can I do make it stop
