On the back pain, did you have have an X-rays or anything? I had both MRI and X-ray in 2009/2010 for wretched low back pain. It said I had degeneration and stenosis. But really, that "diagnoisis" did nothing to help because the surgeon just referred me to pain management.
Well, I hate pain management--so I went to PT instead. That didn't help either (and I was sure it would, since it helped so much after my upper back surgery 10 years ago). Anyway, that's how I ended up in belly dance class. It still took a year of strenghting (I am a slow learner, apparently) but my low back has felt GREAT for over a year now. I remember how the surgeon said nothing could be done for me and I would just have to manage (he meant BEAR) the pain. Sorry for the long the long tirade. I just feel that with the Mirena and everything else there IS a solution--but they are so hard to find!!!
