A white spot? Do you experience blocked ducts? I had a white spot and blocked ducts. Rather painful. For me, I just allow my baby to keep sucking and I also use warm water to shower and massage the affected breast. If your baby dont suck very well yet, you can try pumping. No need to prick with needle bcoz if we dont do it carefully, we may cause infection. If it doesn't get well when you self treat it, maybe you can see a LC. GP and gynaes may not know how to deal with it.
JTS, dont over pump as you'll over stimulate your breasts and get over supply. Its not good to get over supply. I had lots of problem with it last time.
