Just made some kefir today.
Something weird is going on with me. For the last hour or so my left nipple HURTS...sharp pain, it feels like it's being squeezed by blocks of ice, and nothing can warm/sooth it. It just started out of nowhere when I was sitting on the computer. I've had nipple tenderness for the last few weeks now, but only when their pushed/pulled, and nothing resembling this.
Anyone ever heard of/experienced anything like this?
Yes what your describing sounds exactly like Reynauds syndrome. I had it for years when I pumped for my first child. Here is a good link, if you go to the section at the bottom it describes Reynauds nicely. It is also common during pregnancy.
What helped for me was keeping warm overall and away from foods that had constricting properties like coffee.
