I just had this problem about 48hours ago. I did EVERYTHING suggested to help with the engorgement, but nothing worked. I pumped, I had him nurse until he got frustrated there was not enough milk coming out, I hand expressed, I massaged, I took a warm shower, I put on a hot compress for a minute before he nursed, I put on a cold compress afterwards, I took motrin to help with the pain. Then I realized I could see the milk trying to get out, but this white skin was blocking it. I did what I thought was a good idea at the time and just cut open the skin on my nipple with my nails, Now 48hours later he spit up blood. I created a scab and my breast is sore from where I tore the skin, but the engorgement is gone. Now I have been told to put olive oil on the nipple to mostien it and neosporin to keep it from getting infected. I would try to have an LC visit or go to see one at the hospital to see if they can release your milk before you get mastitis.
