Since it is causing pain have they done a scan to be sure it isn't embedded in the uterine wall? I know that was one of the risks they discussed before putting in mine. I think it is rare but it would explain why it hurts.

Hormones are just a disaster for us. I am so glad to be nearly done with menopause and that for whatever reason it started early for me. The mirena solution to the issues from early menopause was rough for the 9 months it was in but when it came out it took one month to know I needed a hysterectomy and while I kept my ovaries so have had natural menopause they cut the blood flow to them so it was faster. My hysterectomy was 3 years ago and I'm down to just one hot flash every few months and very few other hormonal issues. But before that it was bad. I tried being on the pill for a year to regulate my cycle and help me know when I was apt to be extra-moody, early on after diagnosis. That year was such a mess from the hormones and I had no idea that they were the problem because I was new to bipolar and not doing very well with it either.

I hope they get something worked out for you. I feel for your misery and know how hard it is to put up with something that only sort of works. (That was the mirena until we realized how very bad it was. But at least it didn't cause me physical pain, just made me want to die for 9 months and I had a lot of breakthrough bleeding instead of stopping my periods (but it was better than the periods that preceded it).

If you were in the US I'd say insist on a scan to check placement but I know it's not that easy for you. But maybe try to get that done? I saw the thing, it would hurt if it was stuck in muscle tissue.
