If your nipples are hurting then most common cause is a shallow latch. Baby holding the nipple in the mouth and suckling does not mean he is latched well. He needs to be positioned well such that the lower portion of the aerola ( black circular portion around the nipple) goes in. It's a myth that pain will breastfeeding in the beginning is normal.
