I'm sorry that you are in so much pain. It sounds dreadful.
I was watching the Doctors show yesterday and they were talking about
a condition that many women have that sounds similar to yours. You've probably heard of it. Of course, it could be many other things too.
Here is some information that you could read. https://www.mayoclinic.org/diseases-conditions/endometriosis/symptoms-causes/syc-20354656
I hope that you live in a large city. What you really need is to go to a Women's Health Centre or a Women's Hospital. They know more about
women's conditions than a Family Doctor.
I hope that you can get help. My Best to you.
