I would recommend finding a new doctor. Unfortunately, you may have to meet several of them before you find the one who understands this disease.When I moved from FL to NC for a few years, I went to Ob/Gyn who had an office in the hospital. When I mentioned that I had endo, she just looked at me said:"So, you have painful periods." When I told her that majority of my symptoms are actually not during periods, she just blew it off. I never went back to this office. Good luck to you! Hopefully, you have something else that can be easily treated!

That certainly sounds like endo to me, I would seriously consider finding a new doctor, it is so important to be your own patient advocate with this disease because it is so hard to make someone listen, good luck and I hope you can find some answers!
