My wife suffered with this for years.
What helped her was to stop having her period. She went on birth control pills non-stop (doctor prescribed). Instead of taking BC normal with three weeks on and then the one week off with the placebo pills, after week three she opened the next pack and started with pill 1. She rarely gets her period and this has helped quite a bit. There are some BC pills marketed this way like Seasonal or something like that, which make it so you have your period every 3 months. Even that is not as good in the beginning. You need to let your uterus heal. Now if she gets the occasional period (misses a pill or stress will push it through) her pain is no where near where it was.
The fact is every time you have your period it enrages the endo. Stop having your period and you may get some relief. I wouldn't be too worried about any negative side effects, my wife has been doing this for years and so far it has not hurt her. When she wanted to have kids she stopped taking the pills and got pregnant right away. I can tell you that pregnancy helped a lot too, although the first trimester with our first child was very hard on her as her uterus stretched through the scar and endometrial tissue.
It's a very hard thing to deal with, sorry you are having the problem. only other advice I have is to see a fertility specialist instead of a regular OB/GYN. The fertility specialist was the one who helped her the most with managing it.
