First let me say I am sorry to hear of all your trauma. I know how hard it is.
Second, I have a Pituitary Tumor also. It's caused by the Mirena IUD. I know of 3 other people who also have the same thing also caused by the Mirena. You should be seeing an Endocrinologist. I, and the others I know are taking Bromocriptine to shrink the tumor.
You aren't crazy, I can assure you. I have also retained a medical malpractice attorney.
Best of luck and let me know how it goes.
