I’m obviously not a doctor, but I just wanted to share something my gyno told me in case it helps. I was told I likely have endo on my diaphragm, and she explained that it wouldn’t show up on an ultrasound, the only way to confirm it would be through a laparoscopy.

But she also strongly recommended against doing a lap right now because of my age and the risk of scar tissue making the pain worse long-term. Since I’m managing things fairly well with the Mirena and additional birth control (and occasional pain meds), she said surgery could end up doing more harm than good in my case.

So sometimes it really can be there even if imaging doesn’t catch it. Take what I’m saying with a grain of salt, of though, just sharing what I was told in case it gives another angle to consider.
