Does anyone else feel they can attribute worsening back pain to the Mirena? I have a degenerated disc at L5 but the specialist says it doesn't it explains the severity or type of pain I get. I had the Mirena inserted a year ago for adenomyosis symptoms and it's helped with bleeding and has practically cured the IBS (proof it was hormone related!) but I still have rectal and coccyx pain. The worst thing is, I have since developed crippling lumbar pain that radiates to my knees that started some months after having the Mirena put in. Is it just a coincidence or has anyone else had a similar experience?
