I know this hurts, I had that problem too. Does it feel like it has suction if it is just against your skin? You may need to hand express to lessen the engorgement. Put one hand on the top of the breast and one on the bottom up next to your chest. Next roll and press as you move down toward the nipple. If you do this while in a warm to hot shower it will help with the engorgement and then maybe you'll be able to pump again. My first pump was a single and that didn't work for me after 2 or 3 weeks. I went to a double (both at once) and quit having any problems. I don't know why but it worked better for me. Hope this has been helpful. God Bless!
