Endometriosis Support Group
Endometriosis is a common medical condition where the tissue lining the uterus is found outside of the uterus, typically affecting other organs in the pelvis. The condition can lead to serious health problems, primarily pain and infertility. A major symptom of endometriosis is pain, mostly in the lower abdomen, lower back, and pelvic area.

I don't know if you've tried Lupron but the negative effects on health can be so detrimental that it's recommended that it not be taken for more than 6 months. Female organ removal is worse than permanent Lupron. Taking estrogen MAY make life more tolerable but can also be like miracle gro for any remaining endo implants (it's almost impossible to remove ALL endo).
There are also anatomical / physique changes that are permanent and progressive after hysterectomy. The severing of those uterine ligaments will cause your rib cage to gradually fall towards your hip bones causing a big belly and back and hip problems.
Here's a video about the lifelong functions of the female organs -

Some of the women here on DS have had some success controlling their endo symptoms with diet and supplements.
A holistic, integrative, or functional medicine doctor may be helpful. If you go to surgeons, they'll likely recommend surgery including hysterectomy.
Regardless, make 100% sure that you're comfortable with a decision to have organs removed since there's no going back.
Hope this helps!
I know you're fighting for a change and I commend you for doing this for your cause, but when we reach hysterectomy stage we have done EVERYTHING, we don't make this decision lightly at all. And while its amazing what you're doing, sometimes this is what we need to do....our doctors do fight for our organs too. Its great your giving us info, but untill you've lived this life its hard to tell us we shouldn't do it...
Ironically, I only had one day of unrelenting pain before my hyst (from an ovarian cyst) but now live with pain in my back and hips that I know will only get worse. And I now have the not-so-attractive figure (no waist and thick midsection). These consequences of hysterectomy are rarely acknowledged and/or understood. People think that the hormonal sequelae are the only issues.
When it comes to endo in young women, most doctors do try to preserve organs but in older women and women who're done having children, this doesn't seem to be the case.
Good luck with your decision!
Also, something I've always wondered about as far as endo and birth control - Does birth control that reduces the number of periods to 4 per year help endo symptoms?
Check out the Adhesion discussion here. The poster had a hyst for endo in April and debilitating pain returned well before one year post-op and she was back in the operating room last month..
