Thank you so much sarita. This is really amazing. I just asked the question in jest. And oh I am surprised.
@bold Tanu it really seems that though not exact labour pain, but the other twin feels cramps in her stomach too. Not only labour pains, but in some cases the twin will feel the pregnancy symptoms like nausea, dizziness too even if not pregnant.
In short, there are cases where the identical twin feels the physical pain of the other.
