I am week 3 of pumping after the accelerated protocol. I don't have much milk, in the teaspoon quantities, but it is definitely there, and able to be expressed.

However, about 5 minutes or so after I finish pumping I get a pronounced tingly feeling in both breasts. It is like the tingly feeling I get when pumping drops, but much more widespread. It feels just like the let down reflex is described but, there is no milk. Nothing leaks and I cannot express anything by pump or hand. It is much more likely to happen when I have had a long pumping session and hand expressed until I couldn't get any more drops.

Could this be let down, only there's nothing to 'let down' or is it something else? It is not at all painful, but very noticeable, not just a twinge here or there.
