Engorgment HELP

I just had my baby 3 days ago and my boobs are HUGE. I am strictly bottle feeding but my boobs are huge to the point where it’s constant pain and they are rock hard, they constantly leak a steady flow because of how full. I’ve been putting

Cabbage, ice packs and a tight bra but it’s getting worse! Any advice?? I’m tempted to go get a pump and let it all out but doctor says it will make it worse. I can’t even sleep it’s so bad
