Nagkasore. Normal yan and experienced that numerous times with my kids. Use your breastmilk and rub it dun sa area. Also continue to breastfeed. The saliva of your baby and the breastmilk circulating sa mouth will help relieve it. Make sure tama yung latch. Masakit pero kailangan tiisin. Mawawala din yan after a few days. Mas masakit if i-pump mo. You can hand express your milk than using breast pump.
Wag mo munang kaya ipa breastfeed kay lo. Mag pump ka nalang muna pagpahingahin mo muna yan
