Moon,it can be let down pain as well!

Yes every 2 or 3 <u>hours</u>

Then it's engorged breast, you need to pump and take the milk. Is your baby taking milk properly from you?

I don't have soreness is nipples... I feel pain im breasts even cant sleep properly

Moon,i second beccas suggestion. You can try applying homemade ghee as well,just ensure to wipe clean your nipples before every feed. Gradually the soreness will subside,sometimes its due to suckling as well.
