How to manage endo pain??

How do you ladies manage endo symptoms?

I am in SO much pain. I can't sleep. It feels like my uterus and ovaries are trying to break out of my body.

I can't be diagnosed until surgery so the doctor can't really treat anything.

She thinks it's endo, and we've exhausted many other options e.g. IBS, dysmenorrhoea (got an IUD to ease but still have all the same endo symptoms except heavy bleeding), and pregnancy.

I'm just in so much pain I can't focus or do anything at all. I just want to feel like a human being, and be able to function.

I'm not even on the waitlist for surgery yet. I'm still waiting to even see a specialist to try and be put on the endo surgery waitlist. I can't afford private.

If you have any tips on how I can manage the pain at all, even a little, please do tell. I am willing to do just about anything at this point.
