Big hugs. I had similar issues.

I've not read about raynaud's actually causing the tips to die and fall away. People with raynaud's in their fingers and toes don't have that happen?

I think for me the damage was what caused the vasospasm. It's a bit chicken-or-egg. But looking back I think the shape of baby's mouth (palate especially) meant the latch looked fine but wasn't. I guess it makes sense that a baby essentially crushing your nipple with each feed, multiple times per day, would cause vascular problems!

Next time I plan on getting a chiro consult very early on if I have problems.

If it's true raynaud's (as in, that is the root of the problem, not damage causing vasospasm), you could look into taking nifedipine. Not without it's risks though so you'd have to weight it up with your dr.

Hope that helps!
