Anja, thanks for your suggestion. Since I wrote on this forum I started intensive Chinese acupuncture and herbal medicine treatment for endometriosis. The first period I had since starting the treatment was pain free- the first without ambulances or emergency injections in ages, and I'm starting to feel better than I've felt in a long time. I do wish I took the initiative to go to the acupuncturist before I had a laparoscopy- I might have avoided it. But the good news is that I'm well without creepy hormonal weirdness to deal with.
