Im sorry, I had a little difficulty reading your post without the any punctuation, but what I think youre asking is if you should go to the origianl doc, or a new one. As Melissa said, endrometriosis does not mean you cant have children, so he did not make any mistake there. I would go to the first doctor, and if youre not satisfied, you can get a second opinion.
Also know that a spot on the brain could mean nothing serious, and may not have anything to do with your headaches. However, you do need to get it checked out.
I hope you find your answers soon and that you feel better...sending warm thoughts your way...

First off, people with endometriosis can have children. It can just be harder to get pregnant. So don't dismiss the doctor just because of that.
If you are having headaches that debilitating, just make an appointment. You can get the films from your previous MRI at the office you had it done and take them along.
Good luck.
