Hi there. I believe you mean Raynaud's syndrome. This is where blood
vessels become vasoconstricted, causing pain, and blanching of the nipples.
It can happen with hands, feet, etc...in people as well.

I suggest you search for this, as it has been discussed, and there is info
on it in the Lactnet archives.

Search raynaud in lactnet
