I just woke up in pain...I had fallen asleep with my LO nursing on one side and pumping on the other. My LO ate what she needed and fell asleep - no problems. Problem is - I fell asleep with the pump on and I was wearing a hands free pump bra so it kept pumping after I went to sleep. All total I pumped for almost 4 hours straight. Now my nipples are killing me. They are swollen, red and white in color and throbbing. Any suggestions on what to do to help? I'm about to take Tylenol for the pain.
