I posted to you yesterday, but when I submitted it, it disappeared. Then I didn't have time to go back and write it again, so here I am today...
I feel so badly that I kept answering your posts and offering advise with the assumption that your recovery experience was a normal one. It was not until you'd been suffering for quite a long time that I could see that it was far from normal.
I'm glad you're writing to inform people of the importance of getting ALL the testing before having the surgery. I'm also glad that your surgeon finally accepted the fact that he'd made a terrible mistake. A surgeon who goes forward with a Nissen without doing all the testing is incompetent, and obviously not experienced in the Nissen surgery. There are too many variables that can cause problems, and those variables will be discovered with a complete battery of tests.
I wish you all the very best of luck in getting your health back. I'm glad you're headed in the right direction, finally.
