Endometriosis

I'm 18 and was diagnosed with endometriosis when I was 15. They haven't done any scoping as they deem it unnecessary to give me a surgery to prove what they already know. After trying every hormonal birth control option, I learned my body does not tolerate any hormonal birth controls. Due to this, my OB/GYN says she can't help me deal with the pain and bleeding. And she isn't sending me for any tests to locate the endometriosis or determine its severity. Should I seek a second opinion?
