Engorged 😭😥

I had my baby 4 days ago and my boobs are MASSIVE. Super engorged. What are your tips on to relieve the pain!? I've heard of putting cabbage on them. Does that work? When should I put it on? Before or after nursing her? My lactation consultant said I should only pump if it is too discomforting and should only do it for two mins each or else I would make it worse. If I do end up doing that, should I do it while nursing? Like after I switch her to the other breast, pump the one she already nursed on? Help!
