I have been reading this forum now for about 1 1/2 years, and almost everything that you are feeling has been felt by someone on this forum. If you do a search, you will find postings about these symptoms. I am glad that you found a doc who is listening to you and is trying to help you. You can always print some postings here and bring them with you. You can also print a page from the petition website that is at the top of the main Mirena page. It now has over 1000 signatures and tons of stories that your doc may be interested in reading.
The Mirena can do a lot of weird things to your body and I recommend that you have it removed. Best of luck to you !
