Breastfeeding moms with Raynaud's

How are you dealing with the pain? I had Raynaud's pretty bad as a kid in my legs and arms. Now I'm dealing with it pretty bad in my nipples. It feels like glass is cutting through them every time my daughter sucks. I have tried a nipple guard but it didn't help at all. I just feel so defeated. I started taking fish oil pills and that surprisingly helped make it a little more bearable but it still hurts pretty freaking bad. Any tips would be appreciated.
