Engorgment help!!

4 days pp and very engorged ! I’m in so much pain . Baby had full tummy two days after birth from excess fluid and didn’t nurse as frequently until she spat out the fluid. And her latch wasn’t great she has a high pallet and it took a little help to get her on right and still does .She is eating wonderfully now but since that happened my breast are extremely full and backed up which has also caused sore bruised nipples from suckling with the fullness and from her latch issue. Anyone know some major tips to cure this fast ! I need relief and I’m afraid I’ll get an infection too if I don’t solve it soon enough.( btw I’ve already seen a lactation consult at the hospital she helped with the latch but now I’m home and my engorgment is a lot worse)
