UPDATE Help. Im NOT breastfeeding

Today is day 3 being postpartum and I felt my boobs just now and they are hard as a rock. I'm wearing a tight sports bra. Anything i can do to make it go away faster?

UPDATE! I tried the cabbage leaves and I felt instant relief🙌. I think I Might freeze some of them too. Thank you for the advice, ill just stick to this and ibuprofen.💜
