Cracked and bloody nipple help

momma bear • Married PCOS Momma of 5 💜

So, I’m fighting a cracked and bloody nipple on one side. It comes and goes. I’ve tried lanolin. Only to find out, I’m severely allergic. I use breastmilk on it but it still keeps coming back. Do you ladies have any suggestions on how to treat it and stop it from coming back? Help please!
