unfortunately pain management is the only way to go. you could have more elective surgery if more endometrium cells were present but other than that the only 'solution' is to have a hysterectomy unfortunately. are you on the pill? because thats used to help control the growth of endometrium cells and helps alot as you can put off having your period and they are also much lighter which is a relief pain wise. the pill is the best option in terms of stopping the bleeding which happens before hand. hope that helps!
