Hi L.
I would pump a little to relieve the pressure ouch!!! I know how painful this can be. I am a mother of 4 breast fed babies. I was never lucky enough to get allot of milk when I was pumping though.
You can try this remedy!
Cabbage Leaves for Engorgement
Severe engorgement about the third or fourth day after the baby is born can usually be prevented by getting the baby latched on well and drinking well from the very beginning. If you do become engorged, please understand that engorgement diminishes within 1 or 2 days even without any treatment. Continue to breastfeed the baby, making sure he gets on well and nurses well. However, if you should get engorged to the point of severe discomfort, cabbage leaves seem to help decrease the engorgement more rapidly than ice packs or other treatments. If you are unable to get the baby latched on, start cabbage leaves, start expressing your milk and give the expressed milk to the baby by spoon, cup, finger feeding or eyedropper and get help quickly.
Use green cabbage.
Crush the cabbage leaves with a rolling pin if the leaves do not accommodate to the shape of your breast.
Wrap the cabbage leaves around the breast and leave on for about 20 minutes. Twice daily is enough. It is usual to use the cabbage leaf treatment two or three times or less. Some will say to use the cabbage leaves after each feeding and leave them on until they wilt. Some are concerned that such frequent use will decrease the milk supply.
Stop using as soon as engorgement is beginning to diminish and you are becoming more comfortable.
You can use acetaminophen (Tylenol™, others) with or without codeine, ibuprofen, or other medication for pain relief. As with almost all medications, there is no reason to stop breastfeeding when taking analgesics.
Ice packs also can be helpful.
Hope this helps!
Take care
