What kind of surgery did you have?
I had 3 laparoscopies done (this was way back in the 1990s), and none of them helped. They create scar tissue - any surgery does - and the scar tissue can cause more and/or different pain. A lot of your pain will depend on where your endo is - if it's on a nerve, or if it's on your bladder, etc.
If they removed all the endo, you might get some relief, but it can grow back. Are you on any kind of treatment for it, like the birth control pill or anything?

I ended up having a hysterectomy and my ovaries removed, but they aren't doing that as much now, and it's really, your absolute last resort. I also had other issues that contributed.
I'm sorry you're going through this. It's really the most frustrating thing.
