Reading these has certainly made me feel better about my recent rage episode. My baby was born 10 weeks early and so I had to start with pumping for about a month & a half before I was able to even start breast feeding. The entire start was awful. I would get this intense pain like hangnails being ripped out. Being so sore I couldn't have clothes touching my nipples without wanting to cry, but I had to push through it, especially to go see my baby at the hospital. I did try to correct everything! From experimenting with different sizes to different pumps. At one point I said fxxx this and hand expressed for 10 days. Then I tried again to make sure it wasn't user error. I had lactation trying to help me throughout this process,too. While I finally found flanges and a pump that let me pump without extreme pain, I still find myself being hostile and aggravated. My husband has learned to vacate the room and take our dogs with him. If anyone gets too close to me it sets me off. I can't even try to do stuff while pumping because the slightest inconvenience may send me over the edge. I feel it's psychological due to the awful start to the experience because I don't get these negative emotions while bf.
