I've just come across this site and am amazed that so many women are experiencing the same negative symptoms that I have been. I wanted to share my symptoms with you in case you find solace in them like I did reading about others (when I thought I was going mad).
I had the mirena fitted in July 07 following a laparoscopy for endometriosis. I had happily been using the depo injection for 4 years before hand with no symptoms at all.
My endo specialist advised this was the best form of treatment for endo and also the best option for preserving fertility for later in life.
Almost immediately I had excruciatingly painful breasts (which lasted for 9 months) so that high impact exercise was ruled out during that time. My breasts also grew and I'm now a full cup bigger than I was and I'm now almost going into the next cup size (a 2 cup increase).
I have also steadily gained weight despite going to weight watchers religiously and following the program (no cheating!) as well as intensive exercise. I have now put on 6 kgs (1 stone) which is very depressing.
As a result of this constant weight gain I have seen a dietician who has been monitoring my daily food intake, as well as my weight watchers leader, and both feel my food intake is extremely healthy and shouldn't be resulting in this constant gain. I have even been tested for food intolerances to see if this was causing the weight gain, but all tests have come back negative.
I have also been able to feel the coil almost daily, often getting cramping and pain down one leg. It sometimes feels like it catches on something which sends a wave of nausea through me.
As a teenager I suffered terribly from bad acne but went on roacutan to clear it up. Since going on the mirena my acne has slowly but surely returned.
The only benefit for me has been the complete stopping of periods, which have been traditionally heavy and painful, and I can now have sex pain free (but this is probably more due to the laparoscopy than the mirena).
I think the mirena could work wonders for people who are suited to it but it clearly has some very negative side effects for others.
I have become increasingly depressed over my constant weight gain and acne return and I whilst I'm not unhappy that my breasts are now bigger, the pain I experience with them outweighs the positives.
I have a doctors appointment next week and I will be having it removed as I think being happier and weighing less is far more important than period free and fat! I will post an update once it has been removed - fingers crossed it will be about weight loss and improved happiness!
