Why is it that no matter how much I make my baby sick and also I pump, my left boob is still engorged?

My milk came in on Tuesday

& my boobs are still rock hard. Especially my left boob

- I tried the haaakaa with epsom salt

- Warm compress before nursing/pumping

- Hand express

- Warm water in shower while I massage it & hand express

- even let my husband help out

But it’s still rock hard, I’m scared I’ll get mastitis

Any tips??
