Anal pain? Endometriosis?

[snthtcextc.livejournal.com]

Quick background on my menstrual cycle:
Preteen: Fine, average
High school: Was anorexic, lost my period for about two years.
College/married: Period came back, but much heavier flow at first part of cycle. I started to use a menstrual cup.

I was a part of the menstrual cup community for a time and I've heard some people concerned that using the cup may cause endomentriosis.
Since I've been having periods again for about four years I have noticed a change. I have been having severe pains, but they are in the anal/lower back region. I have them on my period. I've had them when not on my period. They are crippling painful. I can not move. They tend to last from 5 to 15 seconds.
I have stopped using the cup and this pain has decreased some. (I am back to pads.)
Has anyone experienced some of this?
I have read some on endometriosis, but also know it is hard to diagnose.
I plan to get a professional opinion soon, too.
Thanks for the open ears.

Eep! Sounds like a whole lot of not fun! Do you have any links to any explanation/theories on the menstrual cup/endomentriosis connection? I've never heard of that before, and since I use a cup I'd kind of like to be informed on if it's something I should worry about...

Sorry I can't help you out any :(

Having read (in brief) the complaint to the FDA regarding the possibility of menstrual cups exacerbating endo and the FDA's reply (http://www.mum.org/fdacups2.htm), which says that they've only had one submitted case where the two seem plausibly connected in any way, I'd be surprised if endo could be caused by cups, because I've gotten the impression that it's caused by several factors, but I suppose it's quite possible that they could potentially worsen symptoms, just as tampons might.

Barring a real study, though, you might not find anyone who can give you a conclusive answer - just that there's a possibility and that if your pain is less when you don't use the cup to stick to pads.

Could it be internal hemmorhoids?
