Depending on patient’s desire to retain uterus for fertility and whether the disease affects the whole of the uterus or only part of the uterus.  If patient wishes to retain uterus for pregnancy then medical treatment is the only option available which may not confer complete symptomatic relief.  However the effect of medical treatment is temporary when the medication is discontinued, the symptoms return.   If fertility is no longer desired then hysterectomy may be the only cure by removing the pathology.  It may be possible to resect the adenomyoma to provide symptomatic relief.
