I'm due to have a hysteroscopy and the merina coil fitted on friday which I am absoloutly dreading! I got a letter through from the doctor a few days ago explaining what he was doing. I previously had a lap which found a serious infection but no endometriosis, he said hes convinced its there though as I have a family history and my symptoms match up. He says he is putting the coil in to treat 'hidden endometriosis' may sound stupid but can endometriosis be in places they cant see? Or is it just they cant find it? I'm so confused, I would prefer to have 10 more laps to find it than one hysteroscopy I'm dreading to try to treat it. Has anyone had any experience with this??
