kk, I think if the memory is strong enough, it might even result in some seepage - perhaps not the milk that would have nurished a baby, (need to check with someone with medical background here) but a seepage never the less.
The feeling, thou years past, that I remember was a definate fullness, especially near feeding time. And most times, once we both became use to it, was an emotionally, a warm calmness; a time apart for just my baby and I to share.
Physically, I often experienced what I believe you mean by 'tingling' but you're right, it was more than that. It was almost as if the act of nursing was causing the now empty womb muscles to tighten and contract. Perhaps nature's way of trying to get our bodies back into shape.
Sorry - there are something things that are simply hard to adequately describe - at least, for me.
