Nipple pain

Sara

So I’ve been breastfeeding for almost 4 months and I get recurring nipple pain on only the right side. It’s not constant, but when it gets bad it gets really bad (and always has). That side always produced less than the other, so I don’t know if it’s because she needs to work harder to get milk. I really want to be able to feed in comfort all the time. Any suggestions on fixing this? I typically add breast shields when it gets bad until it’s better
