I don't think that you've damaged them permanently. It's just a sign that you have very sensitive skin. I have rim marks too that fade away during long hours. And yes when I overpump my breast skin becomes darker than the other body. But I think it'll go away anyway. So don't panic.
Yes it's not beautiful but the whole process of pumping isn't nice at all so I got used to it and try never to overpump. [/align]

I'll try to be hopeful. It's been three days of no pumping and the ring marks are still there. I'll keep massaging in the meantime. Thanks.
