Yep, had vasospasm badly in the early days. Both my nipples would go blue then white and send radiant pain into my breast. The worst was getting out of the shower OMG the pain! My nipples would shrivel and be so painful.

My problem was a VERY strong suck from bub, and a fast flow, so she would slip back on my nipple to cope and then damage the end. It went away once she was old enough to cope with the flow (and my nipples toughened up). It does come back occasionally though when bub is unsettled and I let her chomp on my nipple for comfort - the "boob dummy" idea.

I found a warm face washer really helped after feeds, and to keep the bathroom nice and warm!

HTH
