I've been having vasospasms and nipple blanching for the last two months. I think the cause may be nipple trauma from a combination of pumping and bad latch. When I pump the areola gets sucked into the flange, so when I take the pump off, there's a hard, ring around the base of the nipple on the right areola. My left side doesn't seem to have the same issue. I never realized this could be the problem until 7 months into breastfeeding, because I thought my pain was from thrush or Raynaud's. It dawned on me that I started work two months ago and started pumping regularly. I use a Medela In Style and have switched to the smallest flange (21mm) and put it on the lowest setting to get milk from both sides, but the areola still seems to get sucked in quite a bit. Does anyone have this problem and/or any suggestions on how to fix this? After two months of desperately trying to find out what's causing my pain, I'm starting to think it's hopeless. Thanks!
