Sorry you are having these problems. I hope they can figure things out and get you feeling better. I recently had an expl. lap - and was wondering if they'd find an ovarian remnant syndrome (O.R.S.)situation. (BSO done with hyst but the pain never left). I'm not the right person for hormone advice, but I do know that some of our body fat can produce estrogen, which accounts for why some fluffy women might not require as much replacement. Endo can also produce it's own. Good luck with your tests.
Although most of my "phantom" ovarian pain has been on the left, I also had some very painful episodes of it on the right - to the point I too thought I was experiencing appendicitis. My doc met me at his office during one such episode and said the symptoms didn't quite fit. I knew I didn't have some of the typical symptoms, but it was horrible and when I'd get an episode on the right I could not move without eliciting pain. If I was perfectly still things were better.
I needed a rectocele repaired, so they also decided to do a "second-look" surgery to see what might be causing these "ovarian" pains and pain of my vaginal cuff. We discussed doing an appendectomy while they were in there - so if I had more of these attacks, then I'd at least not have to worry about whether it was the appendix or not.
My doc was delighted to find 2 "smoking guns" as he called them. I had multiple thick adhesions again, but the largest and thickest was around my appendix - pulling it up and over all the way to where it anchored on top of my vaginal cuff --- right next to a large purple endo implant!
Dr. commented that it's not too often they get lucky and find the problem like that.
Bad news is... the pain on the left is still there....along with the endo on my bowel. (sigh)
We'll be thinking of you. Let us know how your appointment goes.
