The let down sensation of milk

I wanted to write what this feels like as it is quite unlike anything I have known before.

Is your let down letting you down?

Let down is the term for describing the flow of breastmilk through the breast to the nipple.  It can happen at anytime, usually when you're out and about having forgotten the indispensable breast pads and wearing a cream silk blouse.

I can only describe the sensation as if my breats were gradually turning to stone as a coldness and hardness seeps from the armpits.  It's not terribly pleasant and is accompanied by the desire to wrap my arms around my chest, close my eyes and count to 30 as the pain passes.  If you're quick enough you can catch the ensuing leakage, but from the start of the sensation you've got less than a minute.  Interestingly each breast functions independently so they don't have to let down at the same time, but for me they work a double act every time.
