I have endometrioma cysts on both of my ovaries. The one on the right is the most painful but also when I lie flat I can see it, well I think I can either that or there is something else in there! When I lie on my tummy it feels like something shouldn't be there, like I am lying on an object. Other times when I lie on my back I get a strange sensation and there is a slight bump low down a little way in from my right hip. This ovary is also adhered to my uterus which is pulled out of place from my endometriosis patches. Maybe this makes it stick out more? I'm not writing this post because it worries me I just wondered if anyone else experiences the same kind of thing. It's just odd!
