Bruised Nipples??

Hello, I am a FTM. I breastfeed and pump. Recently my babe started latching without the shield and I have noticed my nipples are bruised on the ends and are very tender. It makes me not want to breastfeed, and it actually doesn’t hurt as bad when I pump. But when I finish pumping the bruising looks worse. My suction is set very low. I’ve been using lanolin cream and I’m trying the cooling gel pads now. But how can I heal the bruises and stop the pain?
