I trid Lupron injection first. It was very nice. I knew there are possible side-effects but also learned a lot of the bad rap from endo came from women who hadn't tried it. I did pretty well on it.
The second month on lupron is when it kicked in. Started with a headache then got my first hot flash - but my pain was sooo much better that it was worth the trade in side-effects. It was like being on a menstrual vacation. Loved that part of it!
I had an endometrial ablation and myomectomy later. Those failed, so I finally did end up with a hysterectomy. I had planned to keep 1 ovary, but woke with both gone due to how severely involved they were. Stage IV endo, with a frozen pelvis - dense adhesions throughout.
Yes, my endometriosis did return. I had two more surgeries to remove it. Finally, (knock on wood) it seems pretty quiet 90% of the time now. I also had to have surgery for a cystocele and a rectocele - problably due to the hysterectomy.
All in all, I am pleased iwth the results. Menopause is no picnic though. I don't miss my horrific periods - but I tell ya, I feel like I aged a decade the year I had my hyst.
Good luck to you with your health decision.
