to prevent the sore from getting infected, you can do a saline soak. dissolve some salt in
a cup of warm water and dip your <span style = 'background-color: #dae8f4'>nipple</span> in
to it, or put some of the solution on to it.
the final step is to prevent it from happening again. if it happened from pumping, your best bet is to make sure that you use a little bit of olive oil on the base of your nipple
while you pump. it reduces the friction. also, turn down the setting.
