Breast engorgement but low milk supply when pump

My massage therapist taught a method of using a warm towel to massage breasts. She dipped a face towel in (pretty hot) boiled water (but which cooled quite fast on application to breast), and massaged in a direction inward towards the nipple with firm strength. It actually feels quite good. And boobs feel very relieved after the massage. You can try it. Just use a temperature that is tolerable. All the best. And continue to latch. Don't give up. First few days are a torture.

the only way work for me is latch
