Many clinical studies shows- for women with more extensive disease whose quality of life and health are threatened by heavy bleeding and pain, and for whom hormonal
interventions fail, the best treatment until now has been hysterectomy
Now a new study shows that Mirena
may be just as effective as hysterectomy in treating adenomyosis
So in your case, Hormonal treatment with levonorgesterone IUCD (mirena) would be ideal.
Hope this helps.
